Types of Inheritance in C++. The type of inheritance is specified by the access-specifier as explained above. It provides code reusability i.e. 4. and base_class_name is the name of the base class from which you want to inherit the sub class. If we create these classes avoiding inheritance then we have to write all of these functions in each of the three classes as shown in below figure: You can clearly see that above process results in duplication of same code 3 times. Enter value of a=20Enter value of b=30Sum=50. Why Join Become a member Login . 2. The below table summarizes the above three modes and shows the access specifier of the members of base class in the sub class when derived in public, protected and private modes: 1. Let’s take an example: if you live with your parents, then the father will be one base class, and you (as a child) will be the derived class. Amrendra Mehta(M.Tech + 12 years Teaching Exps). In this informative topic, we will see best concept of Inheritance in C++ with Example and how it is important for OOP(Object Oriented Programming) Program.Hope this post will be very helpful for all students of Computer Science 11th,12th , BCA ,MCA and other computer science aspirants. By using our site, you Derived class can access members of base class according to rule of inheritance but base class can’t access member of derived class. If we need to access the data member a of ClassA through the object of ClassD, we must specify the path from which a will be accessed, whether it is from ClassB or ClassC, bco’z compiler can’t differentiate between two copies of ClassA in ClassD.There are 2 ways to avoid this ambiguity: Avoiding ambiguity using scope resolution operator: Using scope resolution operator we can manually specify the path from which data member a will be accessed, as shown in statement 3 and 4, in the above example. When a Derived class inherits only one base class , is known as single inheritance or single level inheritance. Example: Write a program to derive a class from multiple base classes. Here, the number of base classes will be separated by a comma (‘, ‘) and access mode for every base class must be specified. This type of inheritance is the best way to represent the … A class can also inherit properties from more than one class or from more than one level. Enter value of a =10Enter value of b=20Sum=30. Private:- When a base class is inherited in private mode the public and protected members of base class become private members of derived class. Q. Example: write a program in which take the student marks and sum them and show the total marks on-screen using inheritance in c++. Public:– when a base class is inherited in public mode then Public members of base class become public member of derived class and protected members of base class become protected member of derived class. Derived class:- A class which access or inherits the properties of base class  is called derived class. When a Derived class inherits two or more base classes , it is called multiple inheritance. 3 types of inheritance Inheritance type determines the access type of data that will be inherited by the child class. We are providing here set of programs on privately and publicly inheritance. Note: A derived class doesn’t inherit access to private data members.
