What is overriding in c++...?

Question

answer

Answer 1

In any object-oriented programming language, Overriding is a feature that allows a subclass or child class to provide a specific implementation of a method that is already provided by one of its super-classes or parent classes.

Answer 2

consider

class Base {
public:
void foo(){
std::cout << "Hello!";
}
};

and two subclasses

class Derived1 : Base { };

class Derived2 : Base {
public:
void foo(){
std::cout << "haha, I'm overriding Base::foo";
}
};

Now, if you had

Derived1 first;
Derived2 second;

first.foo() will print "Hello", because it inherited the method of the base class. second.foo() will print "haha, I'm overriding Base::foo", because we added a method with the same name, foo, to it, that overrides the method it got from the base class.
