This document discusses inheritance in object-oriented programming. It describes how a derived class can access non-private members of its base class. It also outlines the different types of inheritance in C++, including single inheritance, multilevel inheritance, multiple inheritance, hierarchical inheritance, hybrid inheritance, and multipath inheritance.

- 1. Object Oriented Programming By Noor Wali Khan UOCH
- 2. Access Control and Inheritance • A derived class can access all the non-private members of its base class. • Thus base-class members that should not be accessible to the member functions of derived classes should be declared private in the base class. • We can summarize the different access types according to - who can access them explain in next slide−
- 3. Access Control and Inheritance
- 4. Types of Inheritance • C++ Inheritance Types • C++ supports six types of inheritance as follows: • Single Inheritance • Multilevel Inheritance • Multiple Inheritance • Hierarchical Inheritance • Hybrid Inheritance • Multipath Inheritance
- 5. Single Inheritance • A derived class with only one base class is called single inheritance.
- 6. Multilevel Inheritance. • A derived class with one base class and that base class is a derived class of another is called multilevel inheritance.
- 7. Multiple Inheritance • A derived class with multiple base class is called multiple inheritance
- 8. Hierarchical Inheritance • Multiple derived classes with same base class is called hierarchical inheritance
- 9. Hybrid Inheritance. • Combination of multiple and hierarchical inheritance is called hybrid inheritance.
- 10. Multipath Inheritance • A derived class with two base classes and these two base classes have one common base class is called multipath inheritance
