Question

I'm attempting to convert the Board and CheWin sections into classes. Is there a way to do just that?

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
using System.Threading.Tasks;

namespace TicTacToe
{
class TicTacToe
{
static char[] arr = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9' };
static int player = 1;
static int choice;
static int flag = 0;

static void Main(string[] args)
{
do
{
Console.Clear();
Console.WriteLine("Player 1 : 'X' \nPlayer 2 : 'O'\n");

if (player % 2 == 0)
{
Console.WriteLine("Player 2 Turn");
}
else
{
Console.WriteLine("Player 1 Turn");
}
Console.WriteLine("\n");
Board();
choice = int.Parse(Console.ReadLine());

if (arr[choice] != 'X' && arr[choice] != 'O')
{
if (player % 2 == 0)
{
arr[choice] = 'O';
player++;
}
else
{
arr[choice] = 'X';
player++;
}
}
else
{
Console.WriteLine("Sorry the row {0} is already marked with {1}", choice, arr[choice], "\n");
Console.WriteLine("Please wait a second board is loading again.......");
Thread.Sleep(1000);

}
flag = CheckWin();
} while (flag != 1 && flag != -1);

Console.Clear();
Board();

if (flag == 1)
{
Console.WriteLine("Player {0} has won", (player % 2) + 1);

}
else
{
Console.WriteLine("Game has ended in a draw!!!");

}
Console.ReadLine();
}
private static void Board()
{
Console.WriteLine(" | | ");
Console.WriteLine(" {0} | {1} | {2}", arr[7], arr[8], arr[9]);
Console.WriteLine("___|___|___");
Console.WriteLine(" | | ");
Console.WriteLine(" {0} | {1} | {2}", arr[4], arr[5], arr[6]);
Console.WriteLine("___|___|____");
Console.WriteLine(" | | ");
Console.WriteLine(" {0} | {1} | {2}", arr[1], arr[2], arr[3]);
Console.WriteLine(" | | ");
}

private static int CheckWin()
{
if (arr[1] == arr[2] && arr[2] == arr[3])
{
return 1;
}
else if (arr[4] == arr[5] && arr[5] == arr[6])
{
return 1;
}
else if (arr[7] == arr[8] && arr[8] == arr[9])
{
return 1;
}

else if (arr[1] == arr[4] && arr[4] == arr[7])
{
return 1;
}
else if (arr[2] == arr[5] && arr[5] == arr[8])
{
return 1;
}
else if (arr[3] == arr[6] && arr[6] == arr[9])
{
return 1;
}

else if (arr[1] == arr[5] && arr[5] == arr[9])
{
return 1;
}
else if (arr[3] == arr[5] && arr[5] == arr[7])
{
return 1;
}

else if (arr[1] != '1' && arr[2] != '2' && arr[3] != '3' && arr[4] != '4' && arr[5] != '5' && arr[6] != '6' && arr[7] != '7' && arr[8] != '8' && arr[9] != '9')
{
return -1;
}
else
{
return 0;
}

}

Answer 1

I have modified above code so that all the mentioned functions are changed from static to class Functions. Also changed static variables to class variables.

Note: class TicTacToe is having all the variables and functions. In main(), one object is created of TicTacToe class and play() in TicTacToe is called for playing the game. All references to class variables will be done through "this" keyword to specify the object variables.

KINDLY GIVE THUMBS UP
