What is global variable scope in Linux programming?

Can you explain what global variable scope means in Linux programming?

Sure! In a C program, you can declare a global variable like this: int globalVar = 10; and access it in any function.

Are there any downsides to using global variables?

Yes, global variables can lead to code that is harder to debug and maintain, as they can be modified from anywhere in the program.
