Study Notes
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.
