after the the while loop is finished, i need to declare the player who took the last chip the winner, but i can't figure out how to do that.
Code:
#include <iostream>
#include <iomanip>
#include <string>
#include <math.h>
using namespace std;
int main()

{ 
int num_chips, chips_taken,max_available, initial_number_of_chips;  
string player_1, player_2; 

cout << "\nRules: The game starts with a pile of chips. Each player may only take at\n"; 
cout << "most half of the chips. The player that gets the last chip wins. Good luck."
		 
	 << "\nPlayer 1 please enter your first name:"; 
cin >> player_1;
cout << "\nPlayer 2 please enter your first name:";
cin >> player_2;

cout <<"\nThe current player is " << player_1; 
cout <<"\n How many chips you would like to start with, " << player_1; 
cin >> initial_number_of_chips;
chips_taken=0;
num_chips=initial_number_of_chips-chips_taken;
max_available=num_chips/2;
while (num_chips>1)
{

	max_available=num_chips/2;
	if(num_chips%2!=0)
	{
	(max_available)+=1;
	}

	cout<< "\n"<<player_1<<", it is your turn. There are "<<num_chips<<" available.\n"; 
	cout<<"You may take up to "<<max_available<<". How many would you like to take?";
	cin>>chips_taken;
	while (chips_taken>(max_available) || chips_taken<1) 
	{
	cout<<"\nError: Invalid number of chips. Please try again,";
	cin>>chips_taken;
	}
	if (chips_taken <=num_chips/2 || chips_taken>=1)
	{
	num_chips=num_chips-chips_taken;
	max_available=num_chips/2;
	if(num_chips%2!=0)
	{
	max_available+=1;
	}
	
	cout<<"\n"<<player_2<<", it is your turn. There are "<<num_chips<<" remaining.\n"; 
	cout<<"You may take up to ";

	cout<<max_available<<". How many would you like to take?";
	cin>>chips_taken;
	}
	while (chips_taken>(max_available) || chips_taken<1) 
	{
	cout<<"\nError: Invalid number of chips. Please try again.";
	cin>>chips_taken;
	}
	
	if (chips_taken<=(num_chips)/2|| chips_taken>=1) 
	{
	num_chips=num_chips-chips_taken; 
	}
	


}
return 0;
}
any ideas? thanks for any help.
