Consider the following example, here we are defining member functions inside the class definition: #include <iostream>usingnamespacestd;classExample{private:intval;public:// function to assign valuevoidinit_val(
Member functions can be defined within the class definition or separately using scope resolution operator, : −. Defining a member function within the class definition declares the function inline, even if you do not use the inline specifier. So either you can define Volume() function as below...
A member function that is not declared as static is called a nonstatic member function. The definition of a member function is within the scope of its enclosing class. The body of a member function is analyzed after the class declaration so that members of that class can be used in the ...
Member functions of a class can be defined either outside the class definition or inside the class definition. In both the cases, the function body remains the same, however, the function header is different. Outside the Class: Defining a member function outside a class requires the function...

module definition file. Whenever you declare a class as _export, the compiler treats it as huge (with 32-bit pointers), and exports all of its non-inline member functions and static data members. You get a far this pointer, and your function and ...

To assign a member function to the pointer, the grammar is: fptr= &Foo::f; Of course declaration and initialization can be absorbed by one definition: int (Foo::*fptr) (string) = &Foo::f; To invoke the member function through the pointer, we use the pointer-to-member selection oper...
