The document discusses inheritance in C++, describing it as a process where a child class acquires properties from a parent class, which enhances code reusability and reduces redundancy. It outlines various modes and types of inheritance, including single, multiple, multi-level, hierarchical, and hybrid inheritance, each with specific traits and syntax. Inheritance is crucial for efficient object-oriented programming, enabling better management of similar functionalities across classes.

- 3. What is inheritance ? Inheritance can be defined as a process in which objects of child class acquires properties and characteristics from the parent class. In C++, OOPs concept inheritance is one of the most important feature. The class which inherits the properties is called the derived class, and the class whose properties or characteristics are inherited is called the base class. Inherited properties

- 5. Why do we use inheritance ? Inheritance is used because it helps in removing data redundancy and increases the reusability of code. To understand it, let’s suppose there are two classes two wheeler and four wheeler both of the classes contains similar functions like color() , brand(), Mileage(). Four wheeler Two wheeler Color() Brand() Mileage() Color() Brand() Mileage()
- 6. Why do we use inheritance ? With Inheritance, we inherit both the classes from one base class, i.e. class vehicle.. Now we have to write functions only once as both the classes are now inherited from the base class. Four wheeler Color() Brand() Mileage() Two wheeler Color() Brand() Mileage() Class vehicle Color() Brand() Mileage() Base class
- 7. Modes of inheritance There are three modes of inheritance i.e Public, protected and private. Public mode: In this mode of inheritance the public members of the base class remain public in the derived class, and same goes for protected members. Protected mode: In this mode the public and protected members of the base class will become protected in the derived class. Private mode: In Private mode protected and public members of class will become private in the derived class.
- 8. Types of inheritance There are various types of inheritance in C++ : • Single inheritance • Multiple inheritance • Multi-level inheritance • Heirarchical inheritance • Hybrid inheritance
- 9. Single inheritance In this type of inheritance, there is a single derived class from a single base class. Syntax: Class derived_class : access_modifier Base_class { //body }; Class Base_class Class derived_class
- 10. Multiple inheritance In this type of inheritance, the derived class is inherited from more than one base class. Syntax: Class derived_class : access_modifier Base_class1 , access_modifier Base_class2 { //body }; Class Base_class1 Class derived_class Class Base_class2
- 11. Multi-level inheritance In Multi-level inheritance, the derived class is inherited from another derived class. Syntax: Class Base_class2 : access_modifier Base_class1 { //body }; Class derived_class : access_modifier Base_class2 { //body }; Class Base_class1 Class derived_class Class Base_class2
- 12. Heirarchical inheritance If more than one class is inherited from the base class then it is known as hierarchical inheritance. Syntax: Class derived_class1 : access_modifier Base_class { //body }; Class derived_class2 : access_modifier Base_class { //body }; Class derived_class3 : access_modifier Base_class { //body }; Class Base_class Class derived1 Class derived2 Class derived3
- 13. Hybrid inheritance Hybrid inheritance is implemented by combining more than one type of inheritance. It can be said as the combination of both multilevel and hierarchical inheritance. Class Base_class1 Class derived_class2 Class derived_class1 Class derived_class3
