Passing Variables by Reference to Functions in C++

In this tutorial we gonna learn how return variables from functions in C++,

Commonly, a return will return a single variable only from a function. However, to return more than one variable we need to use a global variables which it considered a poor programming practice.

On the other hand, we can pass the variables to the function by reference so it will be automatically updated once the function done its jog, and this is what we gonna learn here with the C++ Programming Skills Improvement.

Enjoy.
