Конечно! Вот код игры "Крестики-Нолики" на JavaScript, оформленный с использованием разметки Markdown:

// Game initialization
const board = ["", "", "", "", "", "", "", "", ""];
let currentPlayer = "X";
let gameOver = false;

// Function to render the board
function renderBoard() {
    console.clear();
    console.log(` ${board[0]} | ${board[1]} | ${board[2]} `);
    console.log("---|---|---");
    console.log(` ${board[3]} | ${board[4]} | ${board[5]} `);
    console.log("---|---|---");
    console.log(` ${board[6]} | ${board[7]} | ${board[8]} `);
}

// Function to check for a win
function checkWin() {
    const winPatterns = [
        [0, 1, 2], [3, 4, 5], [6, 7, 8],
        [0, 3, 6], [1, 4, 7], [2, 5, 8],
        [0, 4, 8], [2, 4, 6]
    ];
    return winPatterns.some(pattern => 
        board[pattern[0]] === currentPlayer &&
        board[pattern[1]] === currentPlayer &&
        board[pattern[2]] === currentPlayer
    );
}

// Function to handle player moves
function makeMove(position) {
    if (board[position] === "" && !gameOver) {
        board[position] = currentPlayer;
        renderBoard();

        if (checkWin()) {
            console.log(`Игрок ${currentPlayer} выиграл!`);
            gameOver = true;
        } else if (board.every(cell => cell)) {
            console.log("Ничья!");
            gameOver = true;
        } else {
            currentPlayer = currentPlayer === "X" ? "O" : "X";
        }
    } else {
        console.log("Неверный ход. Попробуйте снова.");
    }
}

// Start the game
renderBoard();

// Example usage
makeMove(0); // Player X makes a move at position 0
makeMove(1); // Player O makes a move at position 1
makeMove(4); // Player X makes a move at position 4
makeMove(2); // Player O makes a move at position 2
makeMove(8); // Player X makes a move at position 8

Теперь представлю код игры "Крестики-Нолики" на C++:

#include <iostream>
#include <vector>

using namespace std;

char currentPlayer;
vector<char> board(9, ' ');

void renderBoard() {
    system("clear"); // Для Windows используйте "cls"
    cout << " " << board[0] << " | " << board[1] << " | " << board[2] << endl;
    cout << "---|---|---" << endl;
    cout << " " << board[3] << " | " << board[4] << " | " << board[5] << endl;
    cout << "---|---|---" << endl;
    cout << " " << board[6] << " | " << board[7] << " | " << board[8] << endl;
}

bool checkWin() {
    const int winPatterns[8][3] = {
        {0, 1, 2}, {3, 4, 5}, {6, 7, 8},
        {0, 3, 6}, {1, 4, 7}, {2, 5, 8},
        {0, 4, 8}, {2, 4, 6}
    };

    for (const auto& pattern : winPatterns) {
        if (board[pattern[0]] == currentPlayer &&
            board[pattern[1]] == currentPlayer &&
            board[pattern[2]] == currentPlayer) {
            return true;
        }
    }
    return false;
}

void makeMove(int position) {
    if (board[position] == ' ') {
        board[position] = currentPlayer;
        renderBoard();

        if (checkWin()) {
            cout << "Игрок " << currentPlayer << " выиграл!" << endl;
        } else if (count(board.begin(), board.end(), ' ') == 0) {
            cout << "Ничья!" << endl;
        } else {
            currentPlayer = (currentPlayer == 'X') ? 'O' : 'X';
        }
    } else {
        cout << "Неверный ход. Попробуйте снова." << endl;
    }
}

int main() {
    currentPlayer = 'X';
    renderBoard();

    int move;
    while (true) {
        cout << "Игрок " << currentPlayer << ", введите номер клетки (1-9): ";
        cin >> move;
        makeMove(move - 1);
    }

    return 0;
}
