Where can a local variable be accessed?

Explanation:
Local variables live in the scope where they’re created. When a variable is declared inside a function, it exists only for that function’s execution and can’t be accessed from outside. This containment keeps data private and prevents other parts of the program from reading or changing it unintentionally. If you need to use a value elsewhere, you must return it, pass it as a parameter, or place it in a broader scope. In some languages, block-scoped declarations (like inside loops or blocks) are also confined to that block, reinforcing the idea that a local variable is not accessible outside its defining scope.
