This need to be done in C sharp

Complete the Tic-Tac-Toe game:

Download the game template TicTacToe.zip.

Add Exception throwing to the .Move method as described in the TBD comment.

Add Exception handling to the Main() method as described in the TBD comment.

Complete the Ended method. The game is over when the grid is full or one player has 3 in a row. Humans are very good at recognizing patterns and can see 3 in a row quite easily. Think about how you would write down a step by step process of detecting this and then implement it. You may discuss your ideas in the forums but do not share code.

Here is part of the program that runs it

using System;

namespace TicTacToe { class Program { static void Main() { var game = new Game(); var player = 'X'; while (!game.Ended()) { game.Print();

//Get an integer position Console.Write("Enter your move:"); string input; int position; do { input = Console.ReadLine(); } while (!int.TryParse(input, out position));

//TBD: Handle the Exceptions: //1. Once you have implemented exceptions in game.Move() you must catch the ones you expect to see here //and handle them with suitable error messages //2. Also handle any unexpected exceptions with an "Unknown Error" message. Work out a way to test that code! game.Move(position, player);

//Switch players player = (player == 'X') ? 'O' : 'X'; } } } }

Then here is the program that need to be finshed

using System; using System.Security.Cryptography.X509Certificates;

namespace TicTacToe { internal class Game { char[,] grid = new char[3,3]; public Game() { for (int x = 0; x < 3; x++) { for (int y = 0; y < 3; y++) { grid[x, y] = '.'; } } }

public bool Ended() { //TBD: Determine the 'end' condition return false; }

internal void Move(int position, char player) { //TBD: This function needs validation //1. Position needs to be in the range 0..9 - if not throw an ArgumentException //2. The grid cell needs to be unoccupied - if not throw a BadMoveException // .Net does not have a BadMoveException so you must define a custom exception class

grid[position % 3, (position /3)] = player; }

public void Print() { Console.Clear();

Console.WriteLine("Key"); int cell = 0; for (int y = 0; y < 3; y++) { if (y >= 1) Console.WriteLine("---+---+---"); for (int x = 0; x < 3; x++) { if (x >= 1) Console.Write("|"); Console.Write(" {0} ", cell++); } Console.WriteLine(); }

Console.WriteLine(); for (int y = 0; y < 3; y++) { if (y >= 1) Console.WriteLine("---+---+---"); for (int x = 0; x < 3; x++) { if (x >= 1) Console.Write("|"); Console.Write(" {0} ", grid[x,y]); } Console.WriteLine(); }

}

} }
