What is function overloading is C++ with code example

Function overloading is C++

In function overloading two or more different functions share exactly the same name. That is because in C++  a function is identified by its signature which comprises both the function's name and the list of arguments it takes. Hence the following code is perfectly fine.

#include <iostream>

using namespace std;

void add_some(int y)

{ y += 3;

cout << y << endl;

}

void add_some(double x)

{ x += 1.5;

cout << x << endl;

}

void main() {

      int a=10;

      double b=11.23;

      add_some(a);

      add_some(b);

      system("pause");

}

This is a simple code to understand the concept of function overloading.
