Complete Question:
Create a program that compares the unit prices for two sizes of laundry detergent sold at a grocery store. Console Price Comparison Price of 64 oz size: 5.99 Price of 32 oz size: 3.50 Price per oz (64 oz): 0.09 Price per oz (32 oz): 0.11
Using Python
Answer:
This program does not make use of comments (See explanation section)
price64 = float(input("Price of 64 oz size: "))
price32 = float(input("Price of 32 oz size: "))
unit64 = price64/64
unit32 = price32/32
print("Unit price of 64 oz size: ", round(unit64,2))
print("Unit price of 32 oz size: ", round(unit32,2))
if unit64>unit32:
print("Unit price of 64 oz is greater" )
else:
print("Unit price of 32 oz is greater" )
Explanation:
This line prompts the user for the price of 64 oz size
price64 = float(input("Price of 64 oz size: "))
This line prompts the user for the price of 32 oz size
price32 = float(input("Price of 32 oz size: "))
This line calculates the unit price of 64 oz size
unit64 = price64/64
This line calculates the unit price of 32 oz size
unit32 = price32/32
This next two lines print the unit prices of both sizes
print("Unit price of 64 oz size: ", round(unit64,2))
print("Unit price of 32 oz size: ", round(unit32,2))
The next line compares the unit prices of both sizes
if unit64>unit32:
This line is executed if the unit price of 64 oz is greater than 32 oz
print("Unit price of 64 oz is greater" )
else:
This line is executed, if otherwise
print("Unit price of 32 oz is greater" )
Would these statements cause an error? Why or why not? int year = 2019; int yearNext = 2020; int & ref = year; & ref = yearNext;
Answer: YES
Explanation:
int year=2019;
int yearNext=2020;
int &ref=year;
&ref=yearNext; {This line leads to error as references cannot be reassigned}
(//compilation error: lvalue required as left operand of assignment
) lvalue(&ref) is not something which can be assigned.
To get this better, here are the difference between pointers and reference variables
Pointers
Pointers can be incremented
Array can be formed with pointers
Pointers can be reassigned
Pointer can be declared as void
Reference variable
References cannot be incremented
Array cannot be formed with references
References cannot be reassigned as references shares the address of the variable its assigned
References can never be void

Answer:
#This is in Python
number1 = raw_input("Enter a number: ")
number2 = raw_input("Enter another number: ")
sum = float(number1) + float(number2)
print(sum)
Explanation:
Let's revisit our lucky_number function. We want to change it, so that instead of printing the message, it returns the message. This way, the calling line can print the message, or do something else with it if needed. Fill in the blanks to complete the code to make it work.
def lucky_number(name):
number = len(name) * 9
___ = "Hello " + name + ". Your lucky number is " + str(number)
___
print(lucky_number("Kay"))
print(lucky_number("Cameron"))
Answer:
Replace the first blank with:
message = "Hello " + name + ". Your lucky number is " + str(number)
Replace the second blank with:
return message
Explanation:
The first blank needs to be filled with a variable; we can make use of any variable name as long as it follows the variable naming convention.
Having said that, I decided to make use of variable name "message", without the quotes
The next blank is meant to return the variable on the previous line;
Since the variable that was used is message, the next blank will be "return message", without the quotes
In other to make the function lucky_number return the message rather than print, we use the return keyword.
def lucky_number(name):
number = len(name) * 9
message = "Hello " + name + ". Your lucky number is " + str(number)
return message
In other to return a variable or expression in a defined function such as the lucky_number function defined above, all we have to do is use the return keyword with the message.
When we use :
print(message) : the output when the lucky_number function is called is that, content of the message variable is printed or displayed. However, return message would return message back to the caller making it useful in other parts of our program.The returned value could also be printed using the statement :
print(lucky_number(name)) : This statement prints the content of the returned message variable.

An employee’s total weekly pay equals the hourly wage multiplied by the total number of regular hours, plus any overtime pay. Overtime pay equals the total overtime hours multiplied by 1.5 times the hourly wage. Write a program that takes as inputs the hourly wage, total regular hours, and total overtime hours and displays an employee’s total weekly pay.
Answer:
Assuming this is Python, I would do something like the following:
Explanation:
hourWage= float(input ("What is your hourly wage?: "))
regularHours= float(input ("How many regular hours did you work this week?: "))
overtimeHours= float(input ("How many overtime hours did you have this week?: "))
overtimeWage= (1.5*hourWage)
totalWeeklyPay= (hourWage*regularHours)+(overtimeHours*overtimeWage)
print= ("Your total weekly pay is: " ,totalWeeklyPay)
I hope this works!
Following are the program to calculate weeklyPay value:
Program Explanation:
Defining a variable "Wage, Hour, Hours" that uses the float with the input method to take float value from the user-end.After input value, a "weeklyPay" is declared that calculates the value by the formula.After calculating the value a print method is declared that prints its calculated value.Program:
Wage = float(input("Enter hourly wage: "))#defining a variable Wage that inputs float value
Hour = float(input("Enter total number of regular hours: "))#defining a variable Hour that inputs float value
Hours = float(input("Enter overtime hours: "))#defining a variable Hours that inputs float value
weeklyPay = (Wage*Hour) + (1.5*Wage*Hours)#defining a variable weeklyPay that calculates the values
print (weeklyPay)#defining a print method that prints weeklyPay value

What are the pros and cons of using a linked implementation of a sparse matrix, as opposed to an array-based implementation?
Answer:
Linked lists and arrays are both linear data structures but while an array is a collection of items that can be accessed randomly, a linked list can be accessed sequentially.
A sparse matrix contains very few non-zero elements. For example;
_ _
| 0 0 3 0 6 |
| 0 5 0 0 4 |
| 2 0 0 0 0 |
|_ 0 0 0 0 0 _|
In the implementation of a sparse matrix, the following are some of the pros and cons of using a linked list over an array;
PROS
i. Linked lists are dynamic in nature and are readily flexible - they can expand and contract without having to allocate and/or de-allocated memory compared to an array where an initial size might need to be set and controlled almost manually. This makes it easy to store and remove elements from the sparse matrix.
ii. No memory wastage. Since the size of a linked list can grow or shrink at run time, there's no memory wastage as it adjusts depending on the number of items it wants to store. This is in contrast with arrays where you might have unallocated slots. Also, because the zeros of the sparse matrix need not be stored when using linked lists, memory is greatly conserved.
CONS
i. One of the biggest cons of linked lists is the difficulty in traversing items. With arrays, this is just of an order of 0(1) since the only requirement is the index of the item. With linked lists, traversal is sequential which means slow access time.
ii. Storage is another bottle neck when using linked lists in sparse matrix implementation. Each node item in a linked list contains other information that needs to be stored alongside the value such as the pointer to the next or previous item.

Explanation:
You are in a rectangular maze organized in the form of M N cells/locations. You are starting at the upper left corner (grid location: (1; 1)) and you want to go to the lower right corner (grid location: (M;N)). From any location, you can move either to the right or to the bottom, or go diagonal. I.e., from (i; j) you can move to (i; j + 1) or (i + 1; j) or to (i+1; j +1). Cost of moving right or down is 2, while the cost of moving diagonally is 3. The grid has several cells that contain diamonds of whose value lies between 1 and 10. I.e, if you land in such cells you earn an amount that is equal to the value of the diamond in the cell. Your objective is to go from the start corner to the destination corner. Your prot along a path is the total value of the diamonds you picked minus the sum of the all the costs incurred along the path. Your goal is to nd a path that maximizes the prot. Write a dynamic programming algorithm to address the problem. Your algorithm must take a 2-d array representing the maze as input and outputs the maximum possible prot. Your algorithm need not output the path that gives the maximum possible prot. First write the recurrence relation to capture the maximum prot, explain the correctness of the recurrence relation. Design an algorithm based on the recurrence relation. State and derive the time bound of the algorithm. Your algorithm should not use recursion
Answer:
Following are the description of the given points:
Explanation:
A) The Multiple greedy approaches could exist, which could be to reach for the closest emergency diamond, and yet clearly we are going to miss some very essential routes in that case. So, it can make every argument quickly, and seek to demonstrate a reference case for that.
B) An approach to the evolutionary algorithm and its users are going to just have states M x N. But each state (i, j) indicates the absolute difference between the amount of the selected diamond and the amounts of the costs incurred.
DP(i, j) = DimondVal(i, j) + max ((DP(i, j-1)-2), (DP(i-1,j-1)-3))
DP(i, j) is a description of the state.
DimondVal(i, j) is the diamond value at (i j), 0 if there is no diamond available.
This states must calculate the states of M N and it involves continuous-time for each State to determine. Therefore the amount of time of such an algo is going to be O(MN).
Write a program that create Employee class with fields id,name and sal and create Employee object and store data and display that data.
Answer:
Here is the C++ program for Employee class with fields id,name and sal.
#include <iostream> // to use input output functions
#include <string> //to manipulate and use strings
using namespace std; // to access objects like cin cout
class Employee { //class Employee
private:
/* the following data members are declared as private which means they can only be accessed by the functions within Employee class */
string name; //name field
int id; //id field
double sal; //salary field
public:
Employee(); // constructor that initializes an object when it is created
/* setName, setID and setSalary are the mutators which are the methods used to change data members. This means they set the values of a private fields i.e. name, id and sal */
void setName(string n) //mutator for name field
{ name = n; }
void setId(int i) //mutator for id field
{ id = i; }
void setSalary(double d) //mutator for sal field
{ sal = d; }
/* getName, getID and getSalary are the accessors which are the methods used to read data members. This means they get or access the values of a private fields i.e. name, id and sal */
string getName() //accessor for name field
{ return name; }
int getId() //accessor for id field
{ return id; }
double getSalary() //accessor for sal field
{ return sal; } };
Employee::Employee() { //default constructor where the fields are initialized
name = ""; // name field initialized
id = 0; // id field initialized to 0
sal = 0; } // sal field initialized to 0
void display(Employee);
// prototype of the method display() to display the data of Employee
int main() { //start of the main() function body
Employee emp; //creates an object emp of Employee class
/*set the name field to Abc Xyz which means set the value of Employee class name field to Abc Xyz through setName() method and object emp */
emp.setName("Abc Xyz");
/*set the id field to 1234 which means set the value of Employee class id field to 1234 through setId() method and object emp */
emp.setId(1234);
/*set the sal field to 1000 which means set the value of Employee class sal field to 1000 through setSalary() method and object emp */
emp.setSalary(1000);
display(emp); } //calls display() method to display the Employee data
void display(Employee e) { // this method displays the data in the Employee //class object passed as a parameter.
/*displays the name of the Employee . This name is read or accessed through accessor method getName() and object e of Employee class */
cout << "Name: " << e.getName() << endl;
/*displays the id of the Employee . This id is read or accessed by accessor method getId() and object e */
cout << "ID: " << e.getId() << endl;
/*displays the salary of the Employee . This sal field is read or accessed by accessor method getSalary() and object e */
cout << "Salary: " << e.getSalary() << endl; }
Explanation:
The program is well explained in the comments mentioned with each statement of the program.
The program has a class Employee which has private data members id, name and sal, a simple default constructor Employee(), mutatator methods setName, setId and setSalary to set the fields, acccessor method getName, getId and getSalary to get the fields values.
A function display( ) is used to display the Employee data i.e. name id and salary of Employee.
main() has an object emp of Employee class in order to use data fields and access functions defined in Employee class.
The output of the program is:
Name: Abc Xyz
ID: 1234
Salary: 1000
The program and its output are attached.

A process can be A. single threaded B. multithreaded C. both single threaded and multithreaded D. none of the mentioned
Answer: C. both single threaded and multithreaded
Explanation:
A process can either be single threaded and multithreated. Single threaded processes is when the execution of instructions are in a single sequence i.e the sequence is one command at a time while for multithreaded processes, there are. execution of several multiple parts of a program that occurs at the same time.
A single threaded process only runs on one CPU, whereas for the execution of a multi-threaded, it may be divided amongst the available processors.
ICMP
(a) is required to solve the NAT traversal problem
(b) is used in Traceroute
(c) has a new version for IPv6
(d) is used by Ping
Answer:
(b) is used in Traceroute
(d) is used by Ping
Explanation:
ICMP is the short form of Internet Control Message Protocol. It is a protocol used by networking devices such as routers to perform network diagnostics and management. Since it is a messaging protocol, it is used for sending network error messages and operations information. A typical message could be;
i. Requested service is not available
ii. Host could not be reached
ICMP does not use ports. Rather it uses types and codes. Some of the most common types are echo request and echo reply.
Traceroute - which is a diagnostic tool - uses some messages available in ICMP (such as Time Exceeded) to trace a network route.
Ping - which is an administrative tool for identifying whether a host is reachable or not - also uses ICMP. The ping sends ICMP echo request packets to the host and then waits for an ICMP echo reply from the host.
ICMP is not required to solve NAT traversal problem neither does it have a new version in IPV6.

Driving is expensive. Write a program with a car's miles/gallon (as float), gas dollars/gallon (as float), the number of miles to drive (as int) as input, compute the cost for the trip, and output the cost for the trip. Miles/gallon, dollars/gallon, and cost are to be printed using two decimal places. Note: if milespergallon, dollarspergallon, milestodrive, and trip_cost are the variables in the program then the output can be achieved using the print statement: print('Cost to drive {:d} miles at {:f} mpg at $ {:.2f}/gallon is: $ {:.2f}'.format(milestodrive, milespergallon, dollarspergallon, trip_cost)) Ex: If the input is: 21.34 3.15
Answer:
milespergallon = float(input())
dollarspergallon = float(input())
milestodrive = int(input())
trip_cost = milestodrive / milespergallon * dollarspergallon
print('Cost to drive {:d} miles at {:f} mpg at $ {:.2f}/gallon is: $ {:.2f}'.format(milestodrive, milespergallon, dollarspergallon, trip_cost))
Explanation:
Get the inputs from the user for milespergallon, dollarspergallon and milestodrive
Calculate the trip_cost, divide the milestodrive by milespergallon to get the amount of gallons used. Then, multiply the result by dollarspergallon.
Print the result as requested in the question
Answer:
def driving_cost(driven_miles, miles_per_gallon, dollars_per_gallon):

SONET is the standard describing optical signals over SMF, while SDH is the standard that describes optical signals over MMF fiber.
A. True
B. False
Answer:
False.
Explanation:
SONET is an acronym for synchronous optical networking while SDH is an acronym for synchronous digital hierarchy. They are both standard protocols used for the transmission of multiple digital bit streams (multiplex) synchronously through an optical fiber by using lasers.
Hence, both SONET and SDH are interoperable and typically the same standard protocols in telecommunication networks. Also, the SONET is a standardized protocol that is being used in the United States of America and Canada while SDH is an international standard protocols used in countries such as Japan, UK, Germany, Belgium etc.
The synchronous optical networking was developed in 1985 by Bellcore and it was standardized by the American National Standards Institute (ANSI). SDH was developed as a replacement for the plesiochronous digital hierarchy (PDH).
Generally, SONET comprises of four functional layers and these are;
1. Path layer
2. Line layer.
3. Section layer.
4. Physical or Photonic layer.
The SDH comprises of four synchronous transport modules and these are;
1. STM-1: having a basic data rate of 155.52Mbps.
2. STM-4: having a basic data rate of 622.08Mbps.
3. STM-16: having a basic data rate of 2488.32Mbps.
4. STM-64: it has a basic data rate of 9953.28Mbps.
These two standard telecommunications protocols are used to transmit large amounts of network data over a wide range through the use of an optical fiber.

4. double FindMax(double numi,
5. double num2) { double maxVal; emos

9. maxVal = num1; // then num1 is the maxVal.
10.
11. All tests passed else
12. {maxVal = num2; // Otherwise, // num2 is the maxval.

16. }
17.
18. int main() {
19. double numA;
20. double numB;
21. double numY;
22. double numz;
Answer:
maxSum = FindMax(numA, numB) + FindMax(numY, numZ);
The maxSum is a double type variable which is assigned the maximum of the two variables numA numB PLUS the maximum of the two variables numY numZ using FindMax function. The FindMax() method is called twice in this statement one time to find the maximum of numA and numB and one time to find the maximum of numY numZ. When the FindMax() method is called by passing numA and numB as parameters to this method, then method finds if the value of numA is greater than that of numB or vice versa. When the FindMax() method is called by passing numY and numZ as parameters to this method, then method finds if the value of numY is greater than that of numZ or vice versa. The PLUS sign between the two method calls means that the resultant values returned by the FindMax() for both the calls are added and the result of addition is assigned to maxSum.
Explanation:
This is where the statement will fit in the program.
#include <iostream>
using namespace std;
double FindMax(double num1, double num2) {
double maxVal = 0.0;
if (num1 > num2) { // if num1 is greater than num2,
maxVal = num1; // then num1 is the maxVal. }
else {
maxVal = num2; // num2 is the maxVal. }
return maxVal; }
int main() {
double numA;
double numB;
double numY;
double numZ;
double maxSum = 0.0;
maxSum = FindMax(numA, numB) + FindMax(numY, numZ);
cout << "maxSum is: " << maxSum << endl; }
Lets take an example to explain this. Lets assign values to the variables.
numA = 6.0
numB = 3.0
numY = 4.0
numZ = 9.0
maxSum =0.0
maxSum = FindMax(numA, numB) + FindMax(numY, numZ);
FindMax(numA,numB) method call checks if numA>numB or numB>numA and returns the maximum of the two. Here numA>numB because 6.0 is greater than 3.0. So the method returns numA i.e. 6.0
FindMax(numY, numZ) method call checks if numY>numZ or numZ>numY and returns the maximum of the two. Here numZ>numY because 9.0 is greater than 4.0. So the method returns numZ i.e. 9.0
FindMax(numA, numB) + FindMax(numY, numZ) this adds the two values returned by the method FindMax for each call.
FindMax returned maxVal from numA and numB values which is numA i.e. 6.0.
FindMax returned maxVal from numY and numZ values which is numZ i.e. 9.0.
Adding these two values 9.0 + 6.0 = 15
So the complete statement FindMax(numA, numB) + FindMax(numY, numZ) gives 15.0 as a result.
This result is assigned to maxSum. Hence
maxSum = 15
To see the output on the screen you can use the print statement as:
cout<<maxSum;
This will display 15
The code for function calling is coded below.
To assign the maximum sum of `(numA, numB)` plus the maximum of `(numY, numZ)` to the variable `maxSum` using just one statement, you can call the `FindMax()` function twice in an expression.
Here's the code:
maxSum = FindMax(numA, numB) + FindMax(numY, numZ);
This code calls the `FindMax()` function twice, once with the parameters `(numA, numB)` and again with the parameters `(numY, numZ)`.
It calculates the maximum of each pair of numbers using the `FindMax()` function and then adds the two maximum values together. The result is assigned to the `maxSum` variable.

Based on the information provided it can be said that the best method for sanitizing the data would be Purging. This is a process that permanently erases the data from a specific storage unit. Doing so prevents data from being recovered by an expert and also frees up storage and memory space to be used for other information. Since it is very inexpensive and provides the best overall results this would be the best option in this scenario.
in java how do i Write a method named isEven that accepts an int argument. The method should return true if the argument is even, or false otherwise. Also write a program to test your method.
//Class header definition
public class TestEven {
//Method main to test the method isEven
public static void main(String args[ ] ) {
//Test the method isEven using numbers 5 and 6 as arguments
System.out.println(isEven(5));
System.out.println(isEven(6));
}
//Method isEven
//Method has a return type of boolean since it returns true or false.
//Method has an int parameter
public static boolean isEven(int number){
//A number is even if its modulus with 2 gives zero
if (number % 2 == 0){
return true;
}
//Otherwise, the number is odd
return false;
}
}

Explanation:
The above code has been written in Java. It contains comments explaining every part of the code. Please go through the comments in the code.
A sample output has also been provided. You can save the code as TestEven.java and run it on your machine.
Methods are collections of named program statements that are executed when called or evoked
The program in Java, where comments are used to explain each line is as follows:
import java.util.*;
public class Main {
public static void main(String args[ ] ) {
//This creates a Scanner Object
Scanner input = new Scanner(System.in);
//This gets input for the number
int num = input.nextInt();
//This calls the function
System.out.println(isEven(num));
}
public static boolean isEven(int num){
//This returns true, if num is even
if (num % 2 == 0){
return true;
}
//This returns false, if otherwise
return false;
}
}

I have tried looking for this answer everywhere, and I could not find the answer
I have a Windows 10 Laptop, with a 12GB RAM Card, okay? I also have my 1TB Disk Partitioned so that I have 3 Disks. 2 of them are my primary, both of those are 450GB apiece. The last one ([tex]Z:[/tex]) I named "RAM" and set that one to 100GB.
How do I turn the drive [tex]Z:[/tex] into strictly RAM?
I already did the Virtual Memory part of it, but I was wondering if I can make it strictly RAM so the system uses drive [tex]Z:[/tex] before using the RAM disk? If it is not possible, I'm sorry.
If my computer has 4 gigabytes of ram memory then I have 4e+9 bytes of memory. I think-
Answer: That isn't a software problem, its a hardware problem. There is a difference between 12gb of ram versus 100 gb of HDD. Ram is temporary storage, you can not turn SSD or HDD storage into RAM. If you are a gamer, STEER AWAY FROM LAPTOPS, DO NOT BUY A GAMING LAPTOP. Either buy a DESKTOP (or build) or a console. They give more performance for the price and they are easily upgradable. Not many people can open up a laptop and put in more RAM because the hardware is incredibly small.
Write a program that displays the values in the list numbers in ascendingorder sorted by the sum of their digits.
Answer:
Here is the Python program.
def DigitList(number):
return sum(map(int, str(number)))
list = [18, 23, 35, 43, 51]
ascendList = sorted(list, key = DigitList)
print(ascendList)
Explanation:
The method DigitList() takes value of numbers of the list as parameter. So this parameter is basically the element of the list. return sum(map(int, str(number))) statement in the DigitList() method consists of three methods i.e. str(), map() and sum(). First the str() method converts each element of the list to string. Then the map() function is used which converts every element of list to another list. That list will now contain digits as its elements. In short each number is converted to the string by str() and then the digit characters of each string number is mapped to integers. Now these digits are passed to sum() function which returns the sum. For example we have two numbers 12 and 31 in the list so each digit is 1 2 and 3 1 are added to get the sum 3 and 4. So now the list would have 3 4 as elements.
Now list = [18, 23, 35, 43, 51] is a list of 5 numbers. ascendList = sorted(list, key = DigitList) statement has a sorted() method which takes two arguments i.e. the above list and a key which is equal to the DigitList which means that the list is sorted out using key=DigitList. DigitList simply converts each number of list to a another list with its digits as elements and then returns the sum of the digits. Now using DigitList method as key the element of the list = [18, 23, 35, 43, 51] are sorted using sorted() method. print(ascendList) statement prints the resultant list with values in the list in ascending order sorted by the sum of their digits.
So for the above list [18, 23, 35, 43, 51] the sum of each number is 9 ,5, 8, 7, 6 and then list is sorted according to the sum values in ascending order. So 5 is the smallest, then comes 6, 7, 8 and 9. So 5 is the sum of the number 23, 6 is the sum of 51, 7 is the sum of 43, 8 is the sum of 35 and 9 is the sum of 18. So now after sorting these numbers according to their sum the output list is:
[23, 51, 43, 35, 18]
