二维数组N子棋题目c++

以下是一个简单的二维数组N子棋的C++代码示例：

#include <iostream>
#include <vector>

using namespace std;

const int n = 3; // N子棋的棋盘大小为n*n
char board[n][n]; // 棋盘

// 初始化棋盘
void initBoard() {
    for (int i = 0; i < n; i++) {
        for (int j = 0; j < n; j++) {
            board[i][j] = '-';
        }
    }
}

// 打印棋盘
void printBoard() {
    for (int i = 0; i < n; i++) {
        for (int j = 0; j < n; j++) {
            cout << board[i][j] << " ";
        }
        cout << endl;
    }
}

// 判断是否有玩家获胜
bool isWin(char player) {
    // 检查行
    for (int i = 0; i < n; i++) {
        int count = 0;
        for (int j = 0; j < n; j++) {
            if (board[i][j] == player) {
                count++;
            }
        }
        if (count == n) {
            return true;
        }
    }
    // 检查列
    for (int j = 0; j < n; j++) {
        int count = 0;
        for (int i = 0; i < n; i++) {
            if (board[i][j] == player) {
                count++;
            }
        }
        if (count == n) {
            return true;
        }
    }
    // 检查对角线
    int count1 = 0;
    int count2 = 0;
    for (int i = 0; i < n; i++) {
        if (board[i][i] == player) {
            count1++;
        }
        if (board[i][n-i-1] == player) {
            count2++;
        }
    }
    if (count1 == n || count2 == n) {
        return true;
    }
    return false;
}

int main() {
    initBoard(); // 初始化棋盘
    char player1 = 'X'; // 玩家1执X子
    char player2 = 'O'; // 玩家2执O子
    char currentPlayer = player1; // 当前玩家为玩家1
    bool gameOver = false; // 游戏是否结束
    while (!gameOver) {
        printBoard(); // 打印棋盘
        int row, col;
        cout << "请玩家" << currentPlayer << "输入落子位置(行 列): ";
        cin >> row >> col;
        // 判断位置是否合法
        if (row < 1 || row > n || col < 1 || col > n) {
            cout << "位置不合法，请重新输入！" << endl;
            continue;
        }
        if (board[row-1][col-1] != '-') {
            cout << "该位置已经有棋子，请重新输入！" << endl;
            continue;
        }
        // 在棋盘上落子
        board[row-1][col-1] = currentPlayer;
        // 判断是否有玩家获胜
        if (isWin(currentPlayer)) {
            gameOver = true;
            cout << "恭喜玩家" << currentPlayer << "获胜！" << endl;
        } else {
            // 判断是否平局
            bool isTie = true;
            for (int i = 0; i < n; i++) {
                for (int j = 0; j < n; j++) {
                    if (board[i][j] == '-') {
                        isTie = false;
                        break;
                    }
                }
                if (!isTie) {
                    break;
                }
            }
            if (isTie) {
                gameOver = true;
                cout << "平局！" << endl;
            } else {
                // 切换到下一个玩家
                if (currentPlayer == player1) {
                    currentPlayer = player2;
                } else {
                    currentPlayer = player1;
                }
            }
        }
    }
    printBoard(); // 打印最终棋盘
    return 0;
}

该代码中，initBoard()函数用于初始化棋盘，printBoard()函数用于打印棋盘，isWin()函数用于判断是否有玩家获胜，main()函数则是游戏的主要逻辑。在游戏中，玩家1执X子，玩家2执O子，玩家轮流在棋盘上落子，直到有玩家获胜或者平局。
