Global Variable
Global variables are variables that are declared outside of any function or block of code and can be accessed from any part of the program.

Here are some characteristics, features, advantages, disadvantages, and uses of global variables:
Local and Global Variables
Local variables are declared within a specific block of code, such as a function or method, and have limited scope and lifetime, existing only within that block. Global variables, on the other hand, are declared outside of any function and can be accessed from any part of the program, persisting throughout its execution.
