Volume of variables

Question

Why do local variables use Stack in C / C ++?

Answer 1

Technically, C does not use the stack. If you look at the C99 standard , you will not find a link to the stack. This is probably the same for the C ++ standard, although I have not tested it.

Stacks are simply implementation details used by most compilers to implement C automatic storage semantics.

When a jump occurs, local variables are pushed and a jump is performed. When you return back to the scope, local variables exit.
