Summary  
This chapter covers C++ references, which are aliases for variables that point to the same memory location, allowing direct modification of the original data with safer and more readable syntax than pointers. It also highlights their advantages—such as mandatory initialization, non-nullability, and efficiency—making them ideal for parameter passing without copying.

General domain of usage  
Function parameter passing

Learn what references are in C++. This video explains how references act as aliases for variables, how they differ from pointers, and why they are useful for safer, more readable code. You will see real code examples showing reference declaration and usage in C++ programs. By the end, you'll understand the practical benefits of using references in your own C++ projects! 

-- video metadata (use this info when making a video) -- Cut all examples of code to a minimum. Show only the essential code. Show code no longer than 12 lines. Remove all possible pieces to demonstrate some code feature. You may show not full code that will not start, but still demonstrates some feature theoritacally. If code is longer than 8 lines, move code output  blocks to second column. Avoid using programming language images in the videos.

A **reference** is simply another name for an existing variable. Instead of creating a new variable with its own memory, a reference points to the **same memory location** as the original variable. This means both names work with the **same value**.

So, when you use `referenceVariable`, you are actually working with `originalVariable`.
