Question: Please use a at least one for loop--Thank you for your help
Part 1: Inputs an integer from the user, N.
Part 2: If the integer is not between 0 and 8000000, then the program keeps prompting the user to re-enter the number till the integer is within the proper range.
Part 3: Determine if the number is prime. If N is prime, then print a message stating that it is prime.
Part 4: If the number is not prime, say it is not prime and print out its smallest factor (other than 1).
How to find that number is prime or not?
