Question

(Tic-Tac-Toe) Create class TicTacToe that will enable you to write a complete app to play the game of Tic-Tac-Toe. The class contains a private 3-by-3 rectangular array of integers. The constructor should initialize the empty board to all 0s. Allow two human players. Wherever the first player moves, place a 1 in the specified square, and place a 2 wherever the second player moves. Each move must be to an empty square. After each move, determine whether the game has been won and whether it’s a draw.

I want this in C#

Answer 1

There are 2 files required for this game to run. 1st file is TicTacToe.cs and 2nd is the driver file. Both the file codes are posted below in their respective tables. You are required to create a Windows Console C# Project in visual studio and then create 2 class files named TicTacToe.cs and another as Program.cs and then copy the below codes and paste into these files one by one.

TicTacToe.cs

Program.cs

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace Tic_Tac_Toe { class Program { static void Main(string[] args) { TicTacToe game = new TicTacToe(); game.printInstructions(); int row = 0, col = 0; int winner = 0; while(winner == 0) { game.printBoard(); Console.WriteLine(); if(game.isFirstPlayerTurn()) Console.WriteLine("** Player 1 Turn **"); else Console.WriteLine("** Player 2 Turn **"); Console.WriteLine(); Console.Write("Enter the Row #: "); int.TryParse(Console.ReadLine(), out row); Console.Write("Enter the Column #: "); int.TryParse(Console.ReadLine(), out col); bool validMove = game.selectCell(row, col); if (!validMove) Console.WriteLine("Please re-try."); else { winner = game.checkWinner(); if (winner == 1) { game.printBoard(); Console.WriteLine(" ******* Player 1 wins the Game *******"); }    else if(winner == 2) { game.printBoard(); Console.WriteLine(" ******* Player 2 wins the Game *******"); }    else if(winner == -1) { game.printBoard(); Console.WriteLine(" Oops!
