Function Overloading in C++

Simple example of Function Overloading in C++:

Program Code:

#include <iostream>

using namespace std;

int sum (int x, int y)

{

 cout << x+y;

}

int sum(int x, int y, int z)

{

 cout << x+y+z;

}

int main()

{

sum (10,20);  // sum() with 2 parameter will be called

sum(10,20,30);  //sum() with 3 parameter will be called

}

The output of the program is tested on www.jdoodle.com

Output:

30

60
