« Prev Next »

Function overriding is the main concept in C++ language.

Function Overriding

Function overriding achieved by the same function and the same parameter in base class as well as in derived class. Function overriding used only in different classes.

Syntax:

class A {  
	public:  
		void show(){
         //body of the function. 
        }    
};
class B {  
	public:  
		void show(){
         //body of the function. 
        }    
};
C++ function overloading

Example:

#include <iostream>    
using namespace std;  

class A // base class
{  
	public:  
        void show(){
        	cout << "Base class Function" << endl; 
        }
};  
class B: public A
{  
    public:  
        void show(){
        	cout << "Derived class Function" << endl; 
        }
};       
int main() {  
   B b;
   b.show();
   return 0;
}
