Look at the below diagram in which the three classes are inherited from vehicle class: Page 2. Using inheritance we have to write the functions only one time
C++ allows that a derived class pointer (or reference) to be treated as base class pointer. This is upcasting. Downcasting is an opposite process which
A derived class inherits member functions of base class. • A derived class can be used anywhere the base class is expected. Derived Classes. • A
stud1.inputStudent(); stud1.outputStudent(); stud2.setGpa(3.7); cout << stud2.getGpa();. } Inheritance. Derived class: modifier. Base class.
Constructors of derived classes account for the inheritance. 1. The direct non-virtual base classes By default inheritance in C++ is non-polymorphic.
To diagram a derived class we use a line and a triangle with its point toward and assignment is important in both C and C++ because the rules for.

(2) If base class has a default constructor it is automatically called. (3) Derived class inherits public & protected members access as: derivedclass.
In the case of the copy constructor it is not inherited
