Pass By Value and Pass By Reference in C++ Functions

In the last video, we saw how to create functions in C++, today we will see what is pass by value and pass by reference in function.
A Pass by value parameter, is when the compiler will create a copy of the original value where the function will only work with the copy of the original value and it will not affect the original value.
However, a Pass by reference parameter, is when the function can access directly the original value inside memory, and affect and manipulate the original value.
