Function Overloading in C++

Simple example of Function Overloading in C++ having default  argument:

Program Code:

#include <iostream>

using namespace std;

void sum(int x,int y= 50) // here 50 is a default argument

{

cout << x+y;

}

int main()

{ 

sum(10);

sum(10,0);

sum(10,10);

}

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

Output:

60

10

20
