Program Plan Intro
Static scoping:
This means that the scope of a variable can be determined prior to the execution. So that, compiler can determines the type of every variable in the source code. It provides a method of non-local access of a variable.
Example: ALGOL, Ada, C, and Pascal are statically scoped.
Dynamic scoping:
This means that the scope of a variable is dynamic. That is, it refers to change. The call stack can be different from every time a current function is called, and so the function might have different variables depending on where it is called from.
Example: Common LISP supports dynamic scoping.
