A C++ function declared as a member of a class [N4140 9.3]. This includes static member functions. For example the functionsMyStaticMemberFunctionandMyMemberFunctionin: class MyClass {public:void MyMemberFunction() {DoSomething();}static void MyStaticMemberFunction() {DoSomething();}}; ...
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.
A public member function can also be defined outside of the class with a special type of operator known as Scope Resolution Operator (SRO);SROrepresents by::(double colon) Syntax Consider the following syntax to define member functions outside of the class definition: return_type class_name::...
