Inheritance Mechanism

A mechanism for creating a new class (derived class) from an existing class (base class), inheriting its properties and behaviors.

Base Class

The existing class from which a new class is derived in inheritance.

Derived Class

The new class created by inheriting from a base class.

Multiple Inheritance

A type of inheritance where a derived class inherits from more than one base class.

Study Notes

Inheritance in C++

  • The mechanism of deriving a new class from an old one is called inheritance.
  • The old class is referred to as the base class or parent class in the context of inheritance.
  • The new class derived from an old one is called the derived class or subclass.
  • Multiple inheritance is a type of inheritance that involves deriving a class from more than one base class.
  • The syntax for defining a derived class in C++ is class DerivedClass : access-specifier BaseClass { ... };, where access-specifier is public, private, or protected.
  • Public inheritance in C++ means that the derived class inherits all members of the base class and makes them accessible to the public.
