Write a complete C++ program that is made of three functions main(), primeSum(), and bePrime().

The skeleton of these functions are shown below. //Judge if n is a prime number and return the Boolean result to caller bool bePrime(int n) { Use a loop, better with a logical variable }

//return the sum of all prime numbers less than m int primeSum(int m) { // for loop to traverse all integers from 2 to m // Call bePrime() in the loop body, preferably using an if statement }

int main() { //call primeSum() }

The main function should do the following:

1)Input: Read an integer from the user with proper prompt 2)Processing: Call primeSum() with an assignment statement and save the result in a variable. 3)Output: Print result with proper prompt.
