Redefining, Reloading and Overloading?

Question

What is the fundamental difference between redefining, reloading and overloading? When do they happen?

Answer 1

Redefining - Static methods would be a very good example. Since they belong to the class and not to particular instance, you cannot override them in the child class. When you do override, it would be called REDEFINING the method because now you just create a static method with the same name as that of you base class.

Reloading - http://www.codinglabs.net/tutorial_CppRuntimeCodeReload.aspx

Overloading - When methods within a class have same name but have different return type and either vary in number or type of parameters passed.
