System.out.println("Number of Type 1 candles bought : "+firstN);
System.out.println("Number of Type 2 candles bought : "+secdN);
System.out.println("Number of Type 3 candles bought : "+thirdN);
System.out.println("Total cost is : "+total);
System.out.println("Total burn time is : "+totalT);
double costPerBurn = (totatT * 60) / total;
System.out.println("Cost per minute : "+ costPerBurn);
}
}
Explanation:
The Java program creates a continuous for-loop statement that gets the candle type, price and amount ordered from a switch and accumulates the total cost and burn time of the candles bought and the cost per minute burn of the candles consecutively.
Write a program that asks the user to enter a series of single digit numbers with nothing separating them. Read the input as a C-string or a string object. The program should display the sum of all the single-digit numbers in the string. For example, if the user enters 2514, the program should display 12, which is the sum of 2, 5, 1, and 4. The program should also display the highest and lowest digits in the string.
Answer:
#include <stdio.h>
#include <string.h>
int main(){
char number[100];
printf("Number: ");
scanf("%s", number);
int sum = 0;
for(int i =0;i<strlen(number);i++){
sum+= number[i] - '0';
}
printf("Sum: %d",sum);
return 0;
}
Explanation:
This declares a c string of 100 characters
char number[100];
This prompts user for input
printf("Number: ");
This gets user input
scanf("%s", number);
This initializes sum to 0
int sum = 0;
This iterates through the input string
for(int i =0;i<strlen(number);i++){
This adds individual digits
sum+= number[i] - '0';
}
This prints the calculated sum
printf("Sum: %d",sum);
return 0;
The program that ask the user to enter a series of single digit number and display the sum of all the single digit number, highest number and lowest number is as follows:
x = input("input the series of number: ")
y = []
for i in x:
y += i
integer_map = list(map(int, y))
print(sum(integer_map))
print(max(integer_map))
print(min(integer_map))
The code is written in python.
Code explanation:The first line of code ask the user for the series of numbers. The user input is stored in the variable "x"The y variable is an empty arraywe use the for loop to loop through the users series of number. Then add the looped items to the empty array.Then we map the string of list to an integersFinally, we print the sum , maximum and minimum number of the list.learn more on python program: https://brainly.com/question/16025032?referrer=searchResults
Cell address A4 in a formula means it is a _________Mixed cell reference
A. Relative cell reference
B. Mixed cell reference
C. Absolute cell reference
D. All of the above
Answer:
A. Relative cell reference.
Explanation:
A relative cell reference is like a pointer to a cell or range of cell in Excel. In Excel all cell references, by default, are relative cell references.
In the given instance, the cell address A4 in a formula means it is a relative cell reference. If there would have been a $ sign before A4, then it will be an absolute cell reference. But since, it is without dollar sign, it is a relative cell reference.
Therefore, option A is correct.

A network manager is interested in a device that watches for threats on a network but does not act on its own, and also does not put a strain on client systems. Which of the following would BEST meet these requirements?
a. HIDS
b. NIDS
c. NIPS
d. HIPS
Answer:
Option b (NIDS) is the correct choice.
Explanation:
NIDS helps to detect suspicious internet activity. Throughout order to determine all congestion, along with all network packets, unfaithful user information was indeed probably recommended. They were indeed technologies that are already constructively divided up in less than service providers that ineffectively investigate traffic through the systems on something they have been located.All those other available options aren't closely linked to the scenario in question. Therefore this obvious response is the correct one.

(Numerical Data Representation) How many bits per word are required to represent the following positive decimal integers: a.0 through 100b.0 through 255c.0 through 256d.0 through 10,000,000
Answer:
a. 7 bits
b. 8 bits
c. 9 bits
d. 24 bits
Explanation:
Required
Number of bits per word
The formula to get the number of bits per word is:
[tex]2^n = N[/tex]
Where
n = bits
N = numbers
Solving (a) 0 to 100
There are 101 digits between 0 and 100 (inclusive)
So:
[tex]N = 101[/tex]
Substitute 101 for N in [tex]2^n = N[/tex]
[tex]2^n = 101[/tex]
101 can not be expressed as an exponent of 2.
So, we substitute 101 for the closest number greater than 101 that can be expressed as an exponent of 2.
So:
[tex]2^n = 128[/tex]
Express 128 as an exponent of 2
[tex]2^n = 2^7[/tex]
Apply law of indices
[tex]n = 7[/tex]
Hence, 7 bits are required
Solving (b): 0 through 255
There are 256 digits between 0 and 255 (inclusive)
So:
[tex]N = 256[/tex]
Substitute 256 for N in [tex]2^n = N[/tex]
[tex]2^n = 256[/tex]
Express 256 as an exponent of 2
[tex]2^n = 2^8[/tex]
Apply law of indices
[tex]n = 8[/tex]
Hence, 8 bits are required
Solving (c): 0 through 256
There are 257 digits between 0 and 256 (inclusive)
So:
[tex]N = 257[/tex]
Substitute 257 for N in [tex]2^n = N[/tex]
[tex]2^n = 257[/tex]
257 can not be expressed as an exponent of 2.
So, we substitute 257 for the closest number greater than 101 that can be expressed as an exponent of 2.
So:
[tex]2^n = 512[/tex]
Express 512 as an exponent of 2
[tex]2^n = 2^9[/tex]
Apply law of indices
[tex]n = 9[/tex]
Hence, 9 bits are required
Solving (d): 0 through 10000000
There are 10000001 digits between 0 and 10000000 (inclusive)
So:
[tex]N = 10000000[/tex]
Substitute 10000000 for N in [tex]2^n = N[/tex]
[tex]2^n = 10000000[/tex]
10000000 can not be expressed as an exponent of 2.
So, we substitute 10000000 for the closest number greater than 101 that can be expressed as an exponent of 2.
So:
[tex]2^n = 16777216[/tex]
Express 16777216 as an exponent of 2
[tex]2^n = 2^{24[/tex]
Apply law of indices
[tex]n = 24[/tex]
Hence, 24 bits are required
Consider the classes Food, Cheese, and Velveeta where Cheese is a subclass of Food and Velveeta is a subclass of Cheese. State which of the following lines of code are legal.
Cheese c =new Food( );
Velveeta v =new Food( );
Cheese c =new Velveeta( );
Food f =new Velveeta( );
Food f =new Cheese( );
Answer:
Cheese c =new Velveeta( );
Food f =new Velveeta( );
Food f =new Cheese( );
Explanation:
The super-class is the parent class from which features and attributes are inherited from while the subclass or the child class is the class inheriting from the super or parent class.
In Java, the object instance of a class is created with the syntax;
class_name instance_name = new class_name();
Food is the super or parent class of Cheese (which makes Cheese its subclass) and Cheese is the parent class of Velveeta. The extends keyword is used to denote inheritance.
g Write a program that allows a user to input any text in your program. Using the tools that we have discussed, your program should output how many unique words were in the input and then output how many words were unique.
Answer:
Explanation:
The following function/program is written in Java. It asks the user for a sentence as an input and then splits that sentence into an array of words. Then it creates an arrayList for all of the unique words, comparing each word in the sentence with all of those in the ArrayList. If a word is found in the ArrayList it cancels the loop and moves on the next word in the sentence. Finally, it counts all of the unique words in the ArrayList and prints that total to the screen.
public static void uniqueWords() {
Scanner in = new Scanner(System.in);
System.out.println("Enter a sentence:");
String sentence = in.nextLine();
String words[] = sentence.split(" ");
ArrayList<String> uniqueWords = new ArrayList<>();
for (int x = 0; x < words.length; x++) {
boolean exists = false;
for (int i = 0; i < uniqueWords.size(); i++) {
if (words[x].equals(uniqueWords.get(i))) {
exists = true;
break;
}
}
if (exists == false) {
uniqueWords.add(words[x]);
}
}
System.out.println(uniqueWords.size());
}

The type of control structure that
causes a branch forward at some
point, causing a portion of the
program to be skipped, is:
a selection structure.
O a seguential structure
a repetition structure
a loop structure
Answer:
Selection structure.
Explanation:
In a decision structure (selection structure), there is a branch forward at some point, which causes a portion of the program to be skipped. A loop structure (repetition structure) contains a branch to a previous statement in the program module, which results in a block of statements that can be executed many times.

What are two main components to using functions (there are three from you to choose from)? What do each do? Why are they important?
Answer:
function is a self-contained program segment that carries out some specific, well-defined task. Every C program consists of one or more functions. One of these functions must be called main. Execution of the program always begins by carrying out the instructions contained in main. Note that if a program contains multiple functions then their definitions may appear in any order. The same function can be accessed from several different places within a program. Once the function has carried out its intended action, control is returned to the point from which the function was accessed. Generally speaking, a function processes information passed to it from the calling portion of the program, and returns a single value. Some functions, however, accept information but do not return anything.
A function definition has two principal components: the first line (including the argument declarations), and the so-called body of the function.
The first line of a function takes the general form data-type name(type 1 arg 1, type 2 arg 2, ..., type n arg n)
where data-type represents the data type of the item that is returned by the function, name represents the name of the function, and type 1, type 2, ..., type n represent the data types of the arguments arg 1, arg 2, ..., arg n. The allowable data types for a function are:
int for a function which returns an integer value
double for a function which returns an floating-point value
void for a function which does not return any value
The allowable data types for a function's arguments are int and double. Note that the identifiers used to reference the arguments of a function are local, in the sense that they are not recognized outside of the function. Thus, the argument names in a function definition need not be the same as those used in the segments of the program from which the function was called. However, the corresponding data types of the arguments must always match.
The body of a function is a compound statement that defines the action to be taken by the function. Like a regular compound statement, the body can contain expression statements, control statements, other compound statements, etc. The body can even access other functions. In fact, it can even access itself--this process is known as recursion. In addition, however, the body must include one or more return statements in order to return a value to the calling portion of the program.
A return statement causes the program logic to return to the point in the program from which the function was accessed. The general form of a return statement is:
return expression;
This statement causes the value of expression to be returned to the calling part of the program. Of course, the data type of expression should match the declared data type of the function. For a void function, which does not return any value, the appropriate return statement is simply:
return;
A maximum of one expression can be included in a return statement. Thus, a function can return a maximum of one value to the calling part of the program. However, a function definition can include multiple return statements, each containing a different expression, which are conditionally executed, depending on the program logic.
Note that, by convention, the main function is of type int and returns the integer value 0 to the operating system, indicating the error-free termination of the program. In its simplest form, the main function possesses no arguments. The library function call exit(1), employed in previous example programs, causes the execution of a program to abort, returning the integer value 1 to the operating system, which (by convention) indicates that the program terminated with an error status.
The program segment listed below shows how the previous program factorial.c can be converted into a function factorial(n) which returns the factorial (in the form of a floating-point number) of the non-negative integer n:
double factorial(int n)
{
/*
Function to evaluate factorial (in floating-point form)
of non-negative integer n.
*/
int count;
double fact = 1.;
/* Abort if n is negative integer */
if (n < 0)
{
printf("\nError: factorial of negative integer not defined\n");
exit(1);
}
/* Calculate factorial */
for (count = n; count > 0; --count) fact *= (double) count;
/* Return value of factorial */
return fact;
}

QUESTION 1
Which part of an Ethernet Frame uses a pad to increase the frame field to at least 64 bytes?
Answer:
Data field.
Explanation:
In Computer Networking, data encapsulation can be defined as the process of adding a header to a data unit received by a lower layer protocol from a higher layer protocol during data transmission. This ultimately implies that, the header (segment) of a higher layer protocol such as an application layer, is the data of a lower layer such as a transportation layer in the Transmission Control Protocol and Internet Protocol (TCP/IP).
Basically, an Ethernet Frame is one of the IEEE 802.3 data encapsulation standards.
An Ethernet Frame can be defined as the building blocks or bits contained in a single packet of data that is being transmitted over an Ethernet network or connection. When data are transmitted, a frame check sequence (FCS) containing a 4-bytes is used to detect or check for any error in a frame and to ensure no frame data was corrupted in the course of the transmission.
In the transmission control protocol (TCP), all frames that are being transmitted must have a minimum of 64-bytes in length and as such when small packets are encapsulated, some additional bits referred to as pad are typically used to increase the frame size to at least 64-bytes, which is the minimum size.
Hence, a data field is the part of an Ethernet Frame that uses a pad to increase the frame field to at least 64 bytes.
You are a network technician for a small network. Your ITAdmin workstation just stopped communicating with all other computers in the network. You need to diagnose and fix the problem. The following IP addresses are used in this lab:
Location Computer Name IP Address
Networking Closet CorpServer 172.25.10.10
Office 1 Office 1 172.25.10.60
Office 2 Office 2 172.25.10.61
Support Office Support 172.25.10.62
IT Administration ITAdmin 172.25.10.63
Executive Office Exec 172.25.10.64
Answer:
Ping the other workstations from the IT Admin workstation to confirm that connection has been lost, check the status of the network interface card in the workstation with command ifconfig in the terminal, then reset the connection using ifdown and ifup commands. If the problem is not resolved, check the cable connection.
Explanation:
Ping is an ICMP echo message sent by a network host to another to check for connectivity. If they are connected, the other workstation responds with an ICMP response message.
The ifconfig in Linux systems displays the network adapters and their individual IP configurations. If there is no connection even after the network is reset, then the cable connectors could be the problem.
True or False: The major advantage of Arrays over ArrayLists in Java is the fact that while ArrayLists are fixed in size, an Array can increase or decrease in size as needed.
Answer:
False
Explanation:
It's the other way round actually. Arraylists do not have fixed size and can increase or decrease in size as needed. On the other hand, Arrays are fixed from when they are declared; they have a particular size that number of elements cannot go beyond.
An arraylist in Java is a class that is part of a Java collection framework(java.util) that can have variable sizes and only store objects, not primitive data like strings or integers. An array is a data structure in Java and can store both primitive data and objects, while having a fixed size at declaration.
