Inheritance allows a class to acquire the members of another class. In the following example, the class Square inherits from Rectangle
, specified by a colon. Rectangle then becomes the base class of Square, which in turn becomes a derived class of Rectangle. In addition to its own members, Square gains all accessible members in Rectangle, except for any constructors or destructors.
// Base class (parent class)
class Rectangle
{
public int x = 10, y = 10;
public int GetArea() { return x * y; }
}
// Derived class (child class)
class Square : Rectangle {}
