Project 5 Concepts tested by this program: 1. Learn to organize code within a function 2. Learn to pass data to and return Boolean data from function 3. Use of loop 4. Use file processing Program Prime Numbers A prime number is an integer that is greater than 1 and that is only evenly divisible by itself and 1. For example, the number 5 is prime because it can only be evenly divided by 1 and 5. The number 6, however, is not prime because it can be divided evenly by 1, 2, 3, and 6. Write a function name isPrime, which takes an integer as an argument and returns true if the argument is a prime number, or false otherwise. Demonstrate the function in a complete program that reads in an integer that is less than 3001 stores a list of all the prime numbers from 2 through that number in a file named "PrimeList.txt" and to the standard output.
