Polymorphism

1. Overloading

add(int a, int b);
add(float a, float b);

//function call
add(1,2);
add(1.2,2.3);

2. Overriding

The process of redefining the existing data members present in superClass from a base class using inheritance.

superClass{
    methodOne() {
        cout << "Hi";
    }
};

subClass: public superClass{
    methodOne(){
        cout << "Hello";
    }
};
