| | I Agree to what decepticon said. As the object you've created is for Addition class hence Addme.num1 and Addme.num2 has a seperate box (group) for storing values (which is different from Subtractme.num1 and Subtractme.num2). Hence, the sum will be given by Addme.ExecuteAddition() because you've provided values for Addme.num1 and num2. … |

| | > system("pause"); since your actual problem is solved, I'd like to suggest one more thing. using system("pause") to hold output on screen is a bad idea. use std::cin.get(); or directly cin.get(); //if you have declared using namespace std which is more standard than a system call. you can have a … |
