Please answer this correctly. There are other answers on here but they don't run correctly.

C# programming:

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.

Code so far:

Game.cs:

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(); }

}

} }

Program.cs:

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'; } } } }
