C++ Tutorial for Beginners Ep#20 where we learn about References and Passing by Reference in C++. This will be an introduction to C++ References for Beginners. References allow you to change up and already existing name of a variable while keeping the original variable intact. Passing by reference can help you edit variables outside the scope of a called function. This C++ Tutorial is for Beginners and intended for learning the concepts of C++. Use Visual Studio Code or any text editor to follow along. Make sure to subscribe so you can follow the series.

Learn the different about using & as a Reference operator and the difference between References and Memory Access operators. Passing by Reference is a way to pass a variable into a function scope of a called function so that you can make edits to a variable, structure, or object. This is a great way to be able to edit multiple variables inside a function. Which seemed impossible before learning about pass by reference.
