Programming & Computer Science Answers

This assignment requires a C++ program be written to perform a vote counting and tallying procedure to gauge favorite holiday destinations of individuals. It should present the user with the question and a “ballot” of 5 holiday destinations and an exit/quit option. Once the program is started, it should allow the user to vote multiple times (same as in multiple users using the program to vote). The program should start with a program title and brief instructions on how to vote. It should then ask the user to select an item (vote) from a group of items that are presented. You should use your own choice of holiday destinations. After a vote is cast, incorporate a loop that will allow a new vote to be cast. Keep counters for valid and invalid votes as well as for individual item votes. Print a message informing the user whether that the vote was valid or invalid (No second chance provided to a voter even if the vote is invalid)

Write a program named: SumRange.java

This program will prompt the user for two integer values, a min and a max. Then, calculate the sum of all integers from min to max, including both. Do NOT assume that the first value entered will be smaller than the second. Make sure you check which is the smallest and largest.

Then print the result to the screen.

Here are several sample I/O-s (user input in orange bold italics):

Enter two integers, and I'll tell you the sum of all integers between the two (including both):  5 12

The sum is: 68

Enter two integers, and I'll tell you the sum of all integers between the two (including both):  10 2

The sum is: 54

Enter two integers, and I'll tell you the sum of all integers between the two (including both): -5 -10

The sum is: -45

Enter two integers, and I'll tell you the sum of all integers between the two (including both): -5 5

The sum is: 0

Write a program named: WhileLessThan.java

This program will prompt the user for an integer value greater than or equal to 10.

Write a loop which will execute as long as the user inputs a value less than 10. After getting a valid input, print the value to the screen as shown.

Sample I/O (user input in orange bold italics):

Enter an integer greater than or equal to 10:  3

Enter an integer greater than or equal to 10:  21

You entered: 21

Another sample:

Enter an integer greater than or equal to 10:  -2

Enter an integer greater than or equal to 10: 9

Enter an integer greater than or equal to 10: 10

You entered: 10

================================

 Write a program called AnyHellos. This program should prompt the user for an integer n, then should print the phrase "Hello World" n times. You may assume that n will never be negative. Here is an example of what the program output should look like (user input is in orange bold italics):

How many hellos? 

5

Hello World

Hello World

Hello World

Hello World

Hello World

Your program should run with ANY positive integer n given as input.

NOTE: Place the user input on the new line (just use println in your prompt).

Write an expression that will cause the following code to print "less than 20" if the value of userAge is less than 20.

Differentiate between wired networking and wireless networking and critically outline five major advantages and disadvantages of each.

Cloud computing is an emerging and a good model of delivering computing services for Education by relying on existing technologies such as Internet, web services and virtualization. It offers Richfield substantial cost-saving and more efficient way of providing IT services to the students and staff. Richfield can reduce their IT services cost such as software, hardware, and maintenance of the applications. Following the above statement, critically discuss the three service models of cloud computing, giving examples of where each service model is applied. 

An automated program is required to count the votes received to elect the next union representative for a company. The program must ask how many candidates are registered and the name of each of them, as well as the votes received.

The result of the program will be a matrix that shows the votes received by each candidate, the total of votes received and the percentage that represents that number of votes of the total. In addition, it will present a message with the name of the winning candidate.
