C++ Function Overriding

If derived class defines same function as defined in its base class, it is known as function overriding in C++. It is used to achieve runtime polymorphism. It enables you to provide specific implementation of the function which is already provided by its base class.

C++ Function Overriding Example

Let’s see a simple example of Function overriding in C++. In this example, we are overriding the eat() function.

 #include  using namespace std; class Animal {     public: void eat(){   cout<<“Eating…”;       }     };  class Dog: public Animal   {    public:  void eat()       {          cout<<“Eating bread…”;       }   }; int main(void) {    Dog d = Dog();      d.eat();    return 0; } 

Output:

Eating bread...
