C++ Object-Oriented Programming Concepts

Accessor Functions in C++

• Accessor functions, also known as getter functions, allow controlled access to an object's private and protected data members.
• They provide a way to retrieve the value of a private or protected data member while maintaining encapsulation.

Constructors in C++

• A constructor is a special member function that is automatically called when an object of its class is created.
• Constructors are used to initialize objects with a specific state or values.
• They have the same name as the class and do not have a return type, not even void.

Destructors in C++

• A destructor is a special member function that is automatically called when an object of its class is about to be destroyed.
• Destructors are used to release any resources, such as memory, that an object may have allocated.
• They have the same name as the class, prefixed with a tilde (~), and do not have a return type, not even void.

The 'this' Pointer in C++

• The 'this' pointer is a pointer that holds the memory address of the current object.
• It is used to access the members of the current object within a member function.
• The 'this' pointer is implicitly passed to a non-static member function when it is called.

Test your knowledge of object-oriented programming (OOP) in C++ with questions about accessors, constructors, destructors, and 'this' pointer.
