In the following example,MyGrandChildis derived from classMyChild(which is derived fromMyClass). Example // Base class (parent) classMyClass { public: voidmyFunction() { cout <<"Some content in parent class."; } }; // Derived class (child) ...
Let us take a real life example to understand the concept of inheritance there is a group of fruits so, you need to create classes for Apple, Mango, Banana. The methods are taste(), color() which will be same for all of the three classes. If we create these classes avoiding ...
For Example: In an educational institute, a member can act like a teacher and a student. He may be a student of higher class as well as teaching lower classes. The syntax for declaring a derived class which inherited from more than one base classes is 1 2 3 class der_class_name : ...
