How do I turn my problem to have suboutine. Not so sure how to do it.
#include <iostream>
using namespace std;
int main()
{
int x,y,z;
cout << "Please enter first number: ";
cin >> x;
cout << "Please enter second number: ";
cin >> y;
z = x + y;
cout << "Answer is \n" << z;
return 0;
}
For this small program, I would make the input operation a function.
You'll have to pass the x and y variables by reference is you want a single function call to get both.
Or you could have an input function that just gets one value and returns it.
