Inheritance of Member Variables

• Class Variables and Method Prototypes are inherited
• Variables of the base class also exist in the derived class
• When inheritance is public or protected then any public variable in the base class can be accessed directly by derived class objects
• Private variables of the base class can not be accessed directly by the derived class
• Often indirect access is enough:

Cube::Cube(float side) : Box(side, side, side)
{}

• Private base class data is also accessed by the inherited method Volume()
