/* overriding of functions occurs when one class inherits from another class & it is needed when
* derived class function has to do some added or different job than base class function.
* Overloading can even occur without inheritance as they are in the same scope. Overloading is
* used to have same name function behave differently depending upon he parameters passed
* Overloaded operators are functions with special names the keyword "operator" followed by
* the symbol for the operator being defined e.g "+".
