Member Functions in C++ - (BCA / B.Tech)

Member Functions in C++:

A member function in Object-Oriented Programming (OOP) is a special type of function that is defined inside a class. This function is created to perform operations on the data members of the class. Every class has some data members (also called variables) and some functions that access or modify those data members. These functions are called member functions or class functions.

Definition of a Member Function:

A member function is a function that is defined inside a class and operates on the objects of that same class. A member function can directly work on the data members of the class because it has full access to other parts of the class.

Types of Member Functions:

Simple Member Function: A normal type of function defined inside a class and called through an object.
Constant Member Function: A member function that cannot modify any data member, defined with the `const` keyword.
Static Member Function: This function does not work on any specific object of the class but is common to the entire class. It is defined with the `static` keyword.
Constructor: A special type of member function that is automatically called at the time of an object's creation.
Destructor: A special type of member function that is automatically called at the time of an object's destruction.

Features of Member Functions:

Direct access to class data, encapsulation, overloading, constructors and destructors, and association with a class.

Advantages and Disadvantages of Member Functions:

Advantages: Data security, code reusability, binding data and functions together, and transparent and readable code.

Disadvantages: Complexity, performance overhead in some cases, and potential for disorganized class design if not managed properly.
