Problem Statement Write a program to prompt the user for two integers in the main function. The program must contain three functions. addition() such that it can accept two variables. It calculates and returns addition value. 1. Create function 2. Create function subtraction() such that it can accept two variables. It calculates and returns subtraction value. 3. Create function printAddSub) such that it can accept two variables. It doesn't return a value. This function calls addition(), subtraction() functions. It prints both addition and subtraction value through screen. Please provide a prototype for each function and test the program by calling the print AddSub() function in the main function. Example 1: Example 1: Please enter the first number: 7 Please enter the second number: 10 7+10-17 7-10--3 Goodbye! Example 2: Please enter the first number: 50 Please enter the second number: 50 50+ 50-100 50-50-0 Goodbye! Partial Solution Please try to implement the full source code in your IDE first. The solution is partially provided below. Fill in the blanks to complete the missing parts and make sure to not add an empty space before and after the answer. #include using namespace std; //function prototypes int main() { ] ] int firstNum, secondNum; addition(int, int): prompt and get the user inputs cout<<"Please enter the first number: "; int subtraction(int, int): cin>> firstNum; cout<<"Please enter the second number: " cin >>secondNum; /call the function printAddNSublint, int): return a + b cout << "Goodbye!": return 0; //function implementation int return a-b; (firstNum, secondNum): (int a, int b) { (int a, int b) printAddSublint a, int b) { cout<< a <<"+"<
