Explanation:
I believe that in this scenario, the best option for this data would be a hash table using open addressing with 1,800 entries. Hash tables consume more memory than lists but it makes up for it with much faster response time speeds. This is because hash tables work on a key:value system therefore, the license plate can easily be grabbed from the database extremely quickly by just plugging in the plate number. Doing so will retrieve all of the saved information from that license plate. That is why hash tables have a constant time complexity of O(1)
The data structures that would be most appropriate for this task is; D: a hash table using open addressing with 3,600 entries
What is the Importance of Hash Tables?A hash table is also called a hash map and is defined as a data structure that implements an associative array abstract data type which is basically a structure that can map keys to values.
A hash table uses a hash function to compute an index, also called a hash code, into an array of buckets onto a platform that the desired value can be found.
From the above definitions of a hash function and looking at the question, we can say that the data structure that would be most appropriate for the given task is a hash table using open addressing with 3,600 entries.

Suppose we define a WaitlistEntry as follows:
typedef struct{
int iPriority; /* Priority of the student to be enrolled */
int iStudentID; /* ID of the student */
}
WaitlistEntry;
Below are different implements of a function to create a WaitlistEntry from given iPriority and iStudentID data. Some of these implementations are flawed. Identify them and describe what is wrong with them briefly:
WaitlistEntry createWL( int iPriority, int iStudentlD )
WaitlistEntry w,
w.iPriority iPriority;
w.iStudentlD iStudentlD;
return w;
a. correct
b. incorrect, leaks memory
c. incorrect, syntax error
d. incorrect, data will be overwritten by next function call
Answer:
You have syntax errors, but I don't know if it happened when you posted this question, nevertheless
Explanation:
Correct code:
WaitlistEntry createWL( int iPriority, int iStudentID ) { // Opening Brace
WaitlistEntry w; // Should be ; not ,
w.iPriority = iPriority; // Assign Missing
w.iStudentID = iStudentID; // Assign Missing
return w;
} // Closing Brace
// Also note: iStudentID this actually has an 'l' which is LD. Not ID, this is why I assume these errors happened when posting the question.
You need to write a menu driven program. The program allows a user to enter five numbers and then asks the user to select a choice from a menu. The menu should offer the following four options – 1. Display the smallest number entered 2. Display the largest number entered 3. Display the sum of the five numbers entered 4. Display the average of the five numbers entered
Answer:
In Python:
nums = []
for i in range(5):
num = int(input("Num: "))
nums.append(num)
print("1 - Smallest")
print("2 - Largest")
print("3 - Sum")
print("4 - Average")
menu = int(input("Select menu: "))
if menu == 1:
print("Smallest: ",min(nums))
elif menu == 2:
print("Largest: ",max(nums))
elif menu == 3:
isum = 0
for i in range(5):
isum+=nums[i]
print("Sum: ",isum)
elif menu == 4:
isum = 0
for i in range(5):
isum+=nums[i]
print("Average: ",isum/5)
else:
print("Invalid Menu Selected")
Explanation:
This program uses a list to get inputs for the 5 numbers
Here, the list is initialized
nums = []
This iterates from 1 to 5
for i in range(5):
This gets input for the 5 numbers
num = int(input("Num: "))
This appends each number to the list
nums.append(num)
The next 4 lines represents the menu
print("1 - Smallest")
print("2 - Largest")
print("3 - Sum")
print("4 - Average")
This prompts the user for menu
menu = int(input("Select menu: "))
If menu is 1, print the smallest
if menu == 1:
print("Smallest: ",min(nums))
If menu is 2, print the largest
elif menu == 2:
print("Largest: ",max(nums))
If menu is 3, calculate and print the sum of all inputs
elif menu == 3:
isum = 0
for i in range(5):
isum+=nums[i]
print("Sum: ",isum)
If menu is 4, calculate and print the average of all inputs
elif menu == 4:
isum = 0
for i in range(5):
isum+=nums[i]
print("Average: ",isum/5)
If menu is not 1 to 4, then print invalid menu
else:
print("Invalid Menu Selected")

Calculate The Average of Grades Instructions:
Please read the following problem carefully. You will then logon on to https://www.draw.io/to create a professional diagram. You will put all titles, labels, and save your work using the information below. Please follow the directions:
Destini would like to get a better understanding of her grades in all of her college courses before Spring Break. Instead of using a calculator and paper to calculate her grade, she decided to design a program. She will design a program that will ask her to enter her course name and the number of grades in her grade book. The program will then Read the number of Grades based on what was entered by her, Add up all the Grades, Calculate the Average, and Display Course Name and the Average to Screen. It is important to consider that the number of grades will be different for each course. Using Repetition Control, please design this program.
1. Please Create Flowchart using Draw.10 and Simple Flowchart symbols only (Draw.IO)
2. Pseudocode.
Your unique Flowchart must have the following (See Example Here):
A. Name, Date, and class Name [Top Left of Flowchart)
B. A Title of the Flowchart in Bold [Centered at the top of your flowchart)
C. A Brief Summary of your Flowchart (2 to 3 short sentences describing your flowchart) [Left of Flowchart]
Answer:
The pseudocode is as follows:
Input coursename, numgrades
count = 1; totalgrades = 0
while count <= numgrades:
input grade
totalgrade+=grade
count++
average = totalgrade/count
print(coursename)
print(average)
Explanation:
The solution is as follows:
(1) See attachment for flowchart
(2) See answer section for pseudocode
Explanation
Input coursename and number of grades
Input coursename, numgrades
Initialize count of grades input by the user to 1 and the sum of all grades to 0
count = 1; totalgrades = 0
This loop is repeated while count of grades input by the user is less than or equal to the numgrades
while count <= numgrades:
Input grade
input grade
Add grades
totalgrade+=grade
Increase count by 1
count++
End of loop
Calculate average
average = totalgrade/count
Print coursename
print(coursename)
Print average
print(average)
C. Summary of the flowchart
The flowchart gets coursename and the number of grades from the user. Then it gets the score of each grade, add them up t calculate the average of grades.
Lastly, the course name and the average grades is printed

How is an interpreter different from a compiler?
An interpreter translates and executes code line by line, while a compiler translates all code at once so that it is ready to be executed at any time.
An interpreter translates all code at once so that it is ready to be executed at any time, while a compiler translates and executes code line by line.
An interpreter translates programming code into binary language, while a compiler does not.
An interpreter translates binary language into programming language, while a compiler translates programming language into binary language.
Answer:
An interpreter is quite different from a complier due to the following statement below:
O. An interpreter translates and executes code line by line, while a compiler translates all code at once so that it is ready to be executed at any time.
Explanation:
For an interpreter, it works in translating and execution of the codes line after another line. In a situation where there is a mistake in the code, the next line would not be able to be executed, but rather display error message. On the other hand, compiler translate all codes at once and execute them as a single work.
During its translation of the codes in compiler, should there be any error, it would not be able to execute despite the fact that, the error might be in the last line of the code.

Iconic designs are inspirational and are often copied.
True
False
This is absolutely true. A shining example of this is with smartphones. Before Apple introduced the world to the iPhone, most smartphones had actual keyboards, zero touchscreen capabilities, could barely browse the internet, and had very small displays. After the iPhone was released in 2007, companies immediately scrambled to come out with phones that looked uncannily similar to Apple's. Why? Because Apple's phone was designed well. It's pretty amazing how immediate the shift was. In fact, I recomend you look up "Smartphones before and after iPhone" online. It's pretty cool.

Write each of the following tasks as a SQL statement in a new line (remember that you can source the file to compare the output reference): Use the e_store database Select the total stock of all products in the products table. Alias the column name as total_stock. The resulting table should look like this:
Answer:
The query is as follows:
select sum(stock) as total_stock from products
Explanation:
Required
Return total stock using the alias total_stock from the product table.
The explanation of the query is as follows:
select ----> This implies that data is to be selected from the table
sum(stock) ----> This adds up entries in stock column
as total_stock ---> This represents the alias used for sum(stock)column where
from products ----> The table being queried
Take for instance, the content of the table is:
SN Product Stock
1 Apple 5
2 Orange 3
3 Banana 8
The query will return the following table:

Many companies use telephone numbers like 555-GET-FOOD so the number is easier for their customers to remember. On a standard telephone, the alphabetic letters are mapped to numbers in the following fashion: A, B, and C = 2 D, E, and F = 3 G, H, and I = 4 J, K, and L = 5 M, N, and O = 6 P, Q, R, and S = 7 T, U, and V = 8 W, X, Y, and Z = 9 Write a program that asks the user to enter a 12-character telephone number in the format: XXX-XXX-XXXX. Acceptable characters (X's) are A-Z and a-z. Your program should check for: The length of the phone number is correct. The dashes are included and are in the correct positions. There are no characters in the illegal characters in the string. The application should display the telephone number with any alphabetic characters that appeared in the original translated to their numeric equivalent. If the input string is not entirely correct then you should print an error message. For example, if the user enters 555-GET-FOOD the program should display 555-438-3663. If the user enters 123-456-7890, the program should display 123-456-7890. Rules: You must have one function (in addition to main()) that converts an alphabetic character to a digit. Or you can have one function that coverts all characters to digits. You can make your own function or use a built-in function if one exists.
Answer:
The program in Python is as follows:
def convertt(phone):
splitnum = phone.split ('-')
valid = True
count = 0
err = ""
numphone = ""
if len(phone) != 12:
err = "Invalid Length"
valid = False
elif phone[3] != '-' or phone[7] != '-':
err = "Invalid dash [-] location"
valid = False
while valid== True and count < 3:
for ch in splitnum[count]:

Summary
In this lab, you use what you have learned about searching an array to find an exact match to complete a partially prewritten C++ program. The program uses an array that contains valid names for 10 cities in Michigan. You ask the user to enter a city name; your program then searches the array for that city name. If it is not found, the program should print a message that informs the user the city name is not found in the list of valid cities in Michigan.
The file provided for this lab includes the input statements and the necessary variable declarations. You need to use a loop to examine all the items in the array and test for a match. You also need to set a flag if there is a match and then test the flag variable to determine if you should print the the Not a city in Michigan.message. Comments in the code tell you where to write your statements. You can use the previous Mail Order program as a guide.
Instructions
Ensure the provided code file named MichiganCities.cppis open.
Study the prewritten code to make sure you understand it.
Write a loop statement that examines the names of cities stored in the array.
Write code that tests for a match.
Write code that, when appropriate, prints the message Not a city in Michigan..
Execute the program by clicking the Run button at the bottom of the screen. Use the following as input:
Chicago
Brooklyn
Watervliet
Acme
// MichiganCities.cpp - This program prints a message for invalid cities in Michigan.
// Input: Interactive
// Output: Error message or nothing
#include
#include
using namespace std;
int main()
{
// Declare variables
string inCity; // name of city to look up in array
const int NUM_CITIES = 10;
// Initialized array of cities
string citiesInMichigan[] = {"Acme", "Albion", "Detroit", "Watervliet", "Coloma", "Saginaw", "Richland", "Glenn", "Midland", "Brooklyn"};
bool foundIt = false; // Flag variable
int x; // Loop control variable
// Get user input
cout << "Enter name of city: ";
cin >> inCity;
// Write your loop here
// Write your test statement here to see if there is
// a match. Set the flag to true if city is found.
// Test to see if city was not found to determine if
// "Not a city in Michigan" message should be printed.
return 0;
} // End of main()
Answer:
Replace the comments with:
for(x = 0; x < NUM_CITIES; x++){
if(inCity == citiesInMichigan[x]){ foundIt = true;}
}
if(foundIt){ cout<<"Exists";}
else{cout<<"Does not exists";}
Explanation:
This iterates through the cities
[tex]for(x = 0; x < NUM\_CITIES; x++)\{[/tex]
This checks if current city in the array matches the city input by the user
[tex]if(inCity == citie sIn Michigan[x])\{[/tex] foundIt = true; If yes, foundIt is set to true}
}
If foundIt is true, print "Exists"
if(foundIt){ cout<<"Exists";}
If foundIt is false, print "Does not Exists"
else{cout<<"Does not exists";}

When adding delegates to his mailbox, which role should Joel use if he would like the user to be able to read and create items in a particular folder?
- editor
- publishing editor
- author
- manager
Answer:
publishing editor
Explanation:
In this scenario, the role that he should choose for the delegates would be publishing editor. This role will allow them to create, read, modify, and delete all items within a given folder, and create subfolders. The other options listed either do not give access to create/modify existing files or simply only give all these rights with files that the user creates but not files that already existed in the folder. Therefore, this would be the best role for what Joel wants to accomplish.

Write a function named word_beginnings that has two parameters line a string ch a character Return a count of words in line that start with ch. For the purposes of this exercise a word is preceeded by a space. Hint: add a space to the beginning of line For example if line is 'row row row your raft' and ch is 'r' the value 4 will be returned. Note: You can use lists in this question but try to solve it without lists.
Answer:
The function in Python is as follows:
def word_beginnings(line, ch):
count = 0
lines =line.split(" ")
for word in lines:
if word[0] == ch:
count+=1
return count
Explanation:
This defines the function
def word_beginnings(line, ch):
This initializes count to 0
count = 0
This splits line into several words
lines =line.split(" ")
This iterates through each word
for word in lines:
This checks if the first letter of each word is ch
if word[0] == ch:
If yes, increment count by 1
count+=1
Return count

You will use conditionals, loops, and functions to implement a trigonometric functions calculator.
THE PROBLEM
You must complete the provided Python program to calculate three trigonometric functions based on the user's input. The user can select the following trigonometric functions: 1. Sine, 2. Cosine, and 3. Tangent. The user will input option 4 to exit the program. If the user inputs a number different than 1, 2, 3, or 4, your program must print into the display the following message: Invalid option. Your program will keep asking the user for an option until the user choice is 4 (exit).
Trigonometric functions:
Sine: to calculate the sine of an angle (in radians), you must use the following Maclaurin series (Wikipedia):
sin(x) = ∑[infinity]n=0(−1)nx2n+1(2n+1)!∑n=0[infinity](−1)nx2n+1(2n+1)!
Where x is the value of the angle in radians.
Cosine: to calculate the cosine of an angle (in radians), you must use the following Maclaurin series (Wikipedia):
cos(x) = ∑[infinity]n=0(−1)nx2n(2n)!∑n=0[infinity](−1)nx2n(2n)!
Tangent: For the value of an angle different than 90 or 270 (in degrees), the tangent is:
tan(x) = sin(x)cos(x)sin(x)cos(x)
Where x is the value of the angle in radians.
User-defined Functions:
You must write the definition of the following functions:
factorial: this function receives as a parameter an integer value and returns the factorial of the received value. For a parameter equal to 5, the function returns 120 (5 * 4 * 3 * 2 * 1).
sin: this function receives two parameters (a float representing the value of the angle in radians and an integer value representing the number of terms of the Maclaurin series to be calculated). The function returns the value of the sine of the first parameter calculated with the first n terms of the Maclaurin series for the sine (where n is the second parameter received by the function).
cos: this function receives two parameters (a float representing the value of the angle in radians and an integer value representing the number of terms of the Maclaurin series to be calculated). The function returns the value of the cosine of the first parameter calculated with the first n terms of the Maclaurin series for the cosine (where n is the second parameter received by the function).
degTorad (provided): this function receives as a parameter an integer value representing an angle in degrees and returns the value of the received angle in radians.
printMenu (provided): this function does not receive parameters and does not return a value. The function prints the to STDOUT (display) the menu to be used by the user.
Main program:
The main program is provided in the template file. Please use the comments in the template file to complete your solution.
Input:
Your program takes as initial input one integer value representing the menu option. If the initial input value is a trigonometric function (1, 2, or 3), the program will request two additional inputs (an integer value representing an angle in degrees and the number of terms used in the Maclaurin series). The input statements are provided in the template file.
Output:
The print statements are provided in the template file (do not modify the output messages).
Note:
You can safely assume that the input will always be valid.
