Write a C++ program that lets the users enter positive integer numbers in a loop until the user enters a negative number. The program should check if the number entered is prime or not using a function. The function declaration is: bool isPrime (int n); where n is the integer to be checked. The function should return true if the number is a prime and false otherwise. A prime number is a number that is divisible by 1 and itself only. Examples of prime numbers are: 2, 3, 5,7, 11, 13, 17, 19, 23, 29, 31, etc. Sample Session: (Values in Green are entered by the user) Enter a positive integer (enter a negative integer to stop): 31 This is a prime number Enter a positive integer (enter a negative integer to stop): 16 This is not a prime number Enter a positive integer (enter a negative integer to stop): 22 This is not a prime number Enter a positive integer (enter a negative integer to stop): 43 This is a prime number Enter a positive integer (enter a negative integer to stop): -7667 Thank you!
