C++ Tutorial for Beginners Ep#14 where we learn about Variable Scope and and how to use Variable Scope in C++. Variable Scope can help distinguish variables in your program. Understand what Local & Global Variables and why they are important in C++. Variable Scope in C++ comments can also help delete unnecessary variables once you are finished with them called temp variables. Today we'll explore Variable Scope in depth and understand how and where it is used in C++.

You've used Scope and Scope Variables a bunch of times and probably didn't even realize it. Everything between { } are considered local scope and anything outside the main function or any other function can be considered a global scope variable. We'll go and explore this in more depth and understand C++ Global & Local Scopes, as well as, variables.
