The primary difference between a global variable and a local variable lies in their scope of accessibility. A global variable is defined outside any function, allowing it to be accessed and modified by any function in the program. In contrast, a local variable is defined within a specific function and can only be accessed within that function. This means that local variables are temporary and only exist during the function's execution, while global variables persist throughout the program's lifespan. An interesting fact is that using global variables can lead to code that is harder to debug and maintain, as changes in one part of the program can inadvertently affect others.
