***IN PSUEDOCODE ONLY - not a real programming language!!*** Question: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.  Design a Boolean function called isPrime, that accepts 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 and then displays a message indicating whether the number is prime.  The following modules should be written: - getNumber, that accepts a Ref to an integer, prompts the user to enter a number, and accepts that input - isPrime, that accepts an integer as an argument and returns True if the argument is a prime number, or False otherwise - showPrime, that accepts an integer as an argument , calls isPrime, and displays a message indicating whether the…
