prime numbers a prime number is a number 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 boolean function named is prime which takes an integer as an argument and returns true if the argument is a prime number, or false otherwise. use the function in a program that prompts the user to enter a number then displays a message indicating whether the number is prime. tip: recall that the % operator divides one number by another and returns the remainder of the division. in an expression such as num1 % num2, the % operator will return 0 if num1 is evenly divisible by num
