What Is Variable Scope in C++? (Local vs Global Variables)
In this C++ lesson, you’ll learn Variable Scope: why some variables work only inside a function/block (local scope) and what is global variable and how we defined it.
You'll learn:
What “local variable” means (lives inside a function/block and ends when that scope ends).
What “global variable” means (declared outside main)
Where to declare local and global variables
Mini examples:
Local variable inside main() / inside a function/procedure.
Global variable declared above main().
