Playing With Numbers Program

Feb 20, 2022

Objectives in Practice:

• Develop, compile, and run a C++ program that requires the definition and use of functions that utilize fundamental algorithms studied to perform common tasks, such as finding the max and min of a data set, counting, summing, tracking a previous value, searching and sorting, reading until EOF, etc. in programs to solve problems.

• Transfer a program to the Unix server, use the G++ compiler to compile a program and execute a c++ program that you have written

The Instructions That Were Given for the Project:

• Write a C++ program to run a menu-driven program with the following choices:

  • Compute all the Cousin Prime Pairs less than a number
  • Compute if a number is a Perfect number
  • Quit

• Follow the course coding standards outlined in Coding Standards_ (COP3363 Introduction to Programming in C++ for Majors).docx (Coding Standards) .

• Include the basic header in your program Header for Assignments.docx (Required Header Template) , and print a welcome message to the user.

1. Write a function called getValidUserInputPosNumGT0 that allows a user to enter in an integer and validated that the number is > 0. It must have a pass by reference parameter that will store the value selected by the user.

    void GetValidUserInputPosNumGT0(long int &num);
   

2. Write a function called SumOfDivisors that takes a number as a value parameter. It returns the sum of the divisors of the number.

    long int SumOfDivisors(long int num);
   

3. Write a function called IsPrime that takes a number as a value parameter. It returns true if the number is prime and false otherwise.

    bool IsPrime(long int num);
   

4. Write a function called DisplayCousinPrimes that takes a number as a value parameter. It displays all the cousin prime pairs less than the number. See Cousin Prime Wiki

    void DisplayCousinPrimes(long int num);
   

5. Write a function called Perfect that takes a number as a value parameter. It returns true if the number is perfect and false otherwise. See Perfect Number Wiki

    bool IsPerfect(long int num)
   

6. Add comments wherever necessary.

How to Run the Program:

• Use g++ playingWithNumbers.cpp -o playingWithNumbers.exe and then playingWithNumbers.exe in a Linux terminal to compile and run.
