This is meant to be done in C. Write a program that asks the user to input a single positive integer (use input validation), then determines whether or not the number is prime. If the integer is prime, print a message saying so. Otherwise, calculate the prime factors of the integer. The program should include a function called isPrime() that takes a single integer as an argument and returns a value indicating whether the number is prime or not and a second function called printPrimeFactors() that takes a single integer as an argument and prints the prime factors of that integer. Thanks for the help in advance.
