What is the scope of variables in programming?

What is the scope of variables in programming?

The scope of a variable refers to the context within which it is defined and accessible. It determines where a variable can be used.

Can you explain the difference between local and global scope?

Sure! A local variable is defined within a function and can only be accessed inside that function. A global variable, on the other hand, is defined outside any function and can be accessed from anywhere in the code.

What happens if I try to access a local variable outside its scope?

If you try to access a local variable outside its scope, you'll get an error indicating that the variable is not defined.

Are there any exceptions to these rules?

Yes, in some programming languages, closures can allow access to local variables even after the function has executed.
