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(
A member function of a class is a function that has its definition or its prototype within the class definition like any other variable. It operates on any object of the class of which it is a member, and has access to all the members of a class for that object....
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 function body, even if the member function definition appears before the declaration of...
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. Outside the Class: Defining a member function outside a class requires the function...

But that’s only half of the answer. Since the function call now has an added argument, the member function definition also needs to be modified to accept (and use) this argument as a parameter. Here’s our original member function definition forsetID(): ...
A const data member cannot be initialized at the time of declaration or within the member function definition. To initialize aconstdata member of a class, follow given syntax: Declaration constdata_typeconstant_member_name; Initialization Example of initialization of class's const data member in C++...

In conclusion, what we learned here is: 1. The grammar of pointer-to-member function declaration and definition. 2. The grammar to invoke member functions by pointer-to-member selection operators. 3. Use typedef to write clearer code.
