What is the scope of variables in functions?

What is the scope of variables in functions?

The scope of a variable in a function refers to the context in which that variable is accessible. Variables can be local or global.

Can you explain local and global variables?

Sure! Local variables are defined within a function and can only be accessed inside that function. Global variables are 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 function?

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

Are there any exceptions to this rule?

In some programming languages, you can use closures to access local variables from outside their function, but this is specific to certain contexts.
