Episode 4 : Member Function And Scope Resolution Operator

Scope Resolution Operator

We know the declaration of member function inside the class and now we define the member function  outside the class. Structure of this outside function :

           

function_ruturen_type class_name :: function_name(parameter or argument) {          function_statement ; }

Here we use scope resolution operator ( :: ) for define the function outside the class.

Example :

class simple{ public : int a,b; void add(); }; void simple :: add() { cout<<”Add :”<<a+b; }

At first, we define the function in the class then we the definition of the function written outside the class.
