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.
Let's see a simple example of Function overriding in C++. In this example, we are overriding the eat() function.
#includeusing 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; }
