Object-Oriented Programming
Derived Classes and Inheritance
• Constructors and destructors of derived and
base classes
– We can pass arguments from the constructor in a
derived class to the constructor of its base class
» normally do this to initialize the data members of the base
class
» write a constructor initializer
class square: public geom_obj {
public:
square(float x_C, float y_C, float x,float y)
: geom_obj(x_C, y_C) // con. init.
