I am working on the game of nim. In my code it does not get to the winner output of my game.

#include <iostream>
#include <math.h>
#include <time.h>

using namespace std;

int main() 
{
	int init_size, first_turn, AI, play_turn, comp_turn,count;
	srand(time(NULL));
	init_size = rand() % 100 + 10;
	first_turn = rand() % 1 + 0;
	AI = rand() % 1 + 0;

	while (init_size != 0)
	{
		if (first_turn == 1)
		{
			play_turn = rand() % (init_size / 2) + 1;
			init_size = init_size - play_turn;
			first_turn = 0;
			count = 1;
		}
		if (first_turn == 0)
		{
			comp_turn = rand() % (init_size / 2) + 1;
			init_size = init_size - comp_turn;
			first_turn = 1;
			count = 0;
		}
	}

	if (count == 1)
	{
		cout << "Player Wins" << endl;
	}

	if (count == 0)
	{
		cout << "Computer Wins" << endl;
	}

	return 0;
}

Then likely the while loop is an infinite loop.

Put some cout into that loop or better use debugger to see why.

My guess is init_size goes below zero.

I made the changes as suggested. However it only outputs “computer wins” text.

#include <iostream>
#include <math.h>
#include <time.h>

using namespace std;

int main() 
{
	int init_size, first_turn, AI, play_turn, comp_turn,count;
	srand(time(NULL));
	init_size = rand() % 100 + 10;
	first_turn = rand() % 1 + 0;
	AI = rand() % 1 + 0;

	while (init_size >= 2)
	{
		if (first_turn == 1)
		{
			play_turn = rand() % (init_size / 2) + 1;
			init_size = init_size - play_turn;
			first_turn = 0;
			count = 1;
		}
		if (first_turn == 0)
		{
			comp_turn = rand() % (init_size / 2) + 1;
			init_size = init_size - comp_turn;
			first_turn = 1;
			count = 0;
		}
		cout << init_size << endl;
	}

	if (count == 1)
	{
		cout << "Player Wins" << endl;
	}

	if (count == 0)
	{
		cout << "Computer Wins" << endl;
	}

	return 0;
}

Maybe this:

if (first_turn == 1)
		{
			play_turn = rand() % (init_size / 2) + 1;
			init_size = init_size - play_turn;
			first_turn = 0;
			count = 1;
		}
		if (first_turn == 0)

should be this instead:

if (first_turn == 1)
		{
			play_turn = rand() % (init_size / 2) + 1;
			init_size = init_size - play_turn;
			first_turn = 0;
			count = 1;
		}
		else // if (first_turn == 0)

As it is now, computer does a turn in every round because player sets first_turn = 0;

well I put in the else statement and it worked, thanks!

Yay : )

Using the debugger, you would see both players code gets executed one after another, and instantly notice the reason. ; )

thanks for all the help
