C++ Global Variables. In this video, you will learn about global and local variable scope. Scope refers to the area where a function or variable is visible and accessible to other code. There are 3 main types of scope:

- Function scope is accessible only within the function.
- Block scope, also known as local scope, is accessible only within the block or inner blocks. Examples of blocks include if/else conditions, for loops, while loops.
- File scope, also known as global scope, is accessible within the entire file. This covers all blocks.
