Answer to Question #186209 in C++ for Ayush parashar

Question

Explain the type of polymorphism with code

Answer 1

// C++ program to demonstrate compile polymorphism using method overloading and run time polymorphism using method overriding


#include <iostream>




using namespace std;




//C++ compile time polymorphism using method overloading
class CTPolymorphism
{
    public:
        void add(int x, int y)
        {
            cout<<"The sum of x and y is : "<<x + y<<endl;
        }
        void add( double a, double b)
        {
            cout<<"The sum of x and y is : "<<a + b<<endl;
        }
};




//C++ runtime poloymorphism using method overriding
class RTPolymophismParent
{
    public:
        void greet()
        {
            cout<<"Greetings from parent greet() method class"<<endl;
        }
};
//inherits parent
class RTPolymophismChild: public RTPolymophismParent
{
    public:
        void greet() //greet() method has been overridden by child class
        {
            cout<<"Greetings from child greet() method"<<endl;
        }




};


//Driver code
int main()
{
    //Compile time section
    CTPolymorphism compileTime;
    compileTime.add(30, 50); //Calls add with int params
    compileTime.add(34.2, 60.9);//Calls add with double params




    //Run time section
    RTPolymophismChild runTime;
    runTime.greet(); //This will call child class greet()




    return 0;
