Programming NIM with 2 players

vgdd (8)
Hey! This is my code so far and it works fine but Player 2 cannot win only Player 1. Anyone know how to fix this!








#include <iostream>
#include <string>
using namespace std;
int main()
{
const int total = 13;
int n, mtotal;
bool winner = false;

mtotal = total;

while (!winner)
{
if (mtotal >= 0)
cout << "There are " << mtotal << " sticks" << endl;
cout << "Player 1, pick a number between 1 and 4" << endl;
cin >> n;
if (n >= 1 && n <= 4)
{
cout << "You have removed " << n << " stick(s)" << endl;
mtotal -= n;
}
else
{
cout << " Invalid number" << endl;
}
{
if (mtotal >= 0)
cout << "There are " << mtotal << "sticks" << endl;
cout << "Player 2, pick a number between 1 and 4" << endl;
cin >> n;
if (n >= 1 && n <= 4)
{
cout << "You have removed " << n << " stick(s)" << endl;
mtotal -= n;
}
else
{
cout << " Invalid number " << endl;
}
}

if (mtotal <= 0)
{
winner = true;
cout << " Player 1 wins" << endl;
}

}

system("pause");
}

You don't have any coding done that checks if player 2 wins. Also, you should ONLY check if there are 1 or more sticks to pick, NOT 0. Zero sticks and the game ends.

Here is the game where either player can win, if the opponent takes the last stick.

			{
				winner = true;

		}

	}while(!winner);

	system("pause");
}


Also, you should check if the player tries to take more than the amount of sticks left.
