Working with a basic calculator program

The MYCPP_02 program should have a main() function and an Add() function. The signature and the tasks defined for these two functions are as follows:

• void Main(): This calls the Add() function to calculate 1 + 2 and 3 + 4 and output the results
• int Add(int a, int b): This adds up the two integer parameter values, a and b, and returns the calculation result

So, let’s create a new C++ project, name it MyCPP_02, and then add a new main.cpp file.

Then, type in the following code for main.cpp:

#include <iostream>int Add(int a, int b)
{
  return a + b;
}
void main()
{
  std::cout << "My Calculations" << std::endl;
  int result = Add(1, 2);
  std::cout << "Integer addition: 1 + 2 = "
                << result
