Write a program to check if a number is a prime number. 1) let user input a number 2) check if its legal input (must be greater than 1), if not, ask the user input again until the input is greater than 1. 3) check if the number is prime 4) print "it is prime" or "it is composite". (A natural number (1, 2, 3, 4, 5, 6, etc.) is called a prime number (or a prime) if it is greater than 1 and cannot be written as the product of two smaller natural numbers) prime number only has divisors, 1 and itself.
