Попробуйте свои силы в игре, где ваши навыки программирования на C# станут решающим фактором. Переходите по ссылке 🔰.

Чтобы создать игру «Крестики-нолики» на C#, вы можете использовать двумерный массив для представления игрового поля, а затем использовать цикл, чтобы предложить пользователю ввести свои ходы и соответствующим образом обновить поле.

В качестве альтернативы, можно использовать одномерный массив, для некоторых работа с таким представляется более легкой задачей.

Ниже приведен пример фрагмента кода, демонстрирующий, как сделать простую командную версию игры «Крестики-нолики» на основе одномернного массива:

class Program
    {
        //making array and
        //by default I am providing 0-9 where no use of zero
        static char[] arr = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9' };
        static int player = 1; //By default player 1 is set
        static int choice; //This holds the choice at which position user want to mark
        // The flag variable checks who has won if it's value is 1 then someone has won the match
        //if -1 then Match has Draw if 0 then match is still running
        static int flag = 0;
        static void Main(string[] args)
        {
            do
            {
                Console.Clear();// whenever loop will be again start then screen will be clear
                Console.WriteLine("Player1:X and Player2:O");
                Console.WriteLine("\n");
                if (player % 2 == 0)//checking the chance of the player
                {
                    Console.WriteLine("Player 2 Chance");
