C++ overloading of the plus operator

Question

I want to add 2 objects, by overloading the + operator, but my compiler says there's no matching function to call to point::point(int, int). Can somebody please help me with this code, and explain the error ? thank you

#include <iostream>

using namespace std;

class point{
int x,y;
public:
  point operator+ (point & first, point & second)
    {
        return point (first.x + second.x,first.y + second.y);
    }
};

int main()
{
    point lf (1,3)
    point ls (4,5)
    point el = lf + ls;
    return 0;
}

You can just change your code like this,

#include <iostream>

using namespace std;

class point {
    int x, y;
public:
    point(int i, int j)
    {
        x = i;
        y = j;
    }

    point operator+ (const point & first) const
    {
        return point(x + first.x, y + first.y);
    }

};

int main()
{
    point lf(1, 3);
    point ls(4, 5);
    point el = lf + ls;

    return 0;
}

Hope this helps...
