Constructor Overloading in C

Question

My C++ overloading does not work as I expect it to:

#include "Node.h"
#include <iostream>

Node::Node()
{
    cout << "1" << endl;
    Node(Game(), 0.0);
}

Node::Node(double v)
{
    cout << "2" << endl;
    Node(Game(),v);
}

Node::Node(Game g, double v)
{
    cout << "3" << endl;
    numVisits = 0;
    value = v;
    game = g;
}

And the output from:

Node n(16);
cout << n.value << endl;

is zero when it should be sixteen.

What exactly am I doing wrong?
