Advantages of global variable
- Accessibility: Global variables provide a convenient way to share data across different parts of the program without passing them as function arguments.
- Ease of Use: They simplify the sharing of data between functions and modules, reducing the need for complex parameter passing mechanisms.
- Persistence: Global variables retain their values throughout the entire execution of the program, making them suitable for storing persistent data.
- Reduced Code Duplication: Global variables can help reduce code duplication by centralizing data that is used in multiple parts of the program.
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.
