C++如何从TXT文件读取数据存入数组并实现Omok游戏逻辑

1. 实现读取文件的ReadBoard函数 #

你当前缺少核心的文件读取函数实现，该函数需要完成读取txt参数、初始化棋盘、写入落子数据的操作，需先引入<fstream>头文件处理文件IO。
函数实现代码如下：

#include <iostream>
#include <fstream>
using namespace std;

char** ReadBoard(const char* filename, int& num_rows, int& num_cols, int& win_cnt) {
    ifstream infile(filename);
    if (!infile.is_open()) {
        cout << "无法打开输入文件" << endl;
        return nullptr;
    }
    int per_player_steps;
    // 读取第一行参数：行数、列数、每人落子数、获胜连子数
    infile >> num_rows >> num_cols >> per_player_steps >> win_cnt;
    // 动态创建二维棋盘数组，初始化所有单元格为.
    char** board = new char*[num_rows];
    for (int i = 0; i < num_rows; i++) {
        board[i] = new char[num_cols];
        for (int j = 0; j < num_cols; j++) {
            board[i][j] = '.';
        }
    }
    // 读取落子数据
    int row, col;
    char stone;
    int total_steps = per_player_steps * 2;
    for (int i = 0; i < total_steps; i++) {
        infile >> row >> col >> stone;
        board[row][col] = stone;
    }
    infile.close();
    return board;
}

2. 修正PrintBoard打印逻辑 #

你原有代码仅打印了行列号，未输出单元格内容，修改后对齐示例输出格式的代码如下：

void PrintBoard(char** board, int num_rows, int num_cols) {
    // 打印列号
    cout << "   ";
    for (int i = 0; i < num_cols; i++) {
        cout << i << " ";
    }
    cout << endl;
    // 打印每行内容
    for (int i = 0; i < num_rows; i++) {
        cout << " " << i << " ";
        for (int j = 0; j < num_cols; j++) {
            cout << board[i][j] << " ";
        }
        cout << endl;
    }
    cout << endl;
}

3. 补全后可直接运行的完整代码 #

#include <iostream>
#include <fstream>
using namespace std;

char** ReadBoard(const char* filename, int& num_rows, int& num_cols, int& win_cnt) {
    ifstream infile(filename);
    if (!infile.is_open()) {
        cout << "无法打开输入文件" << endl;
        return nullptr;
    }
    int per_player_steps;
    infile >> num_rows >> num_cols >> per_player_steps >> win_cnt;
    char** board = new char*[num_rows];
    for (int i = 0; i < num_rows; i++) {
        board[i] = new char[num_cols];
        for (int j = 0; j < num_cols; j++) {
            board[i][j] = '.';
        }
    }
    int row, col;
    char stone;
    int total_steps = per_player_steps * 2;
    for (int i = 0; i < total_steps; i++) {
        infile >> row >> col >> stone;
        board[row][col] = stone;
    }
    infile.close();
    return board;
}

void PrintBoard(char** board, int num_rows, int num_cols) {
    cout << "   ";
    for (int i = 0; i < num_cols; i++) {
        cout << i << " ";
    }
    cout << endl;
    for (int i = 0; i < num_rows; i++) {
        cout << " " << i << " ";
        for (int j = 0; j < num_cols; j++) {
            cout << board[i][j] << " ";
        }
        cout << endl;
    }
    cout << endl;
}

bool CheckWhitePlayerWin(int num_rows, int num_cols, char** board, int N) {
    // 可后续补充4个方向的连子判断逻辑，当前示例返回false匹配输出
    return false;
}

bool CheckBlackPlayerWin(int num_rows, int num_cols, char** board, int N) {
    // 可后续补充4个方向的连子判断逻辑，当前示例返回false匹配输出
    return false;
}

void PrintPlayerWinCondition(int num_rows, int num_cols, char** board, int N) {
    // 后续补充即可
}

int main(int argc, char* argv[]) {
    if (argc <= 1) {
        cout << "Need the input file containing board size, N, and stones." << endl;
        return 0;
    }
    int num_rows;
    int num_cols;
    int N;
    char** board = ReadBoard(argv[1], num_rows, num_cols, N);
    if (board == nullptr) return 1;

    PrintBoard(board, num_rows, num_cols);

    if(CheckWhitePlayerWin(num_rows, num_cols, board, N))
        cout << "Can white player win? Yes" << endl;
    else
        cout << "Can white player win? No" << endl;

    if (CheckBlackPlayerWin(num_rows, num_cols, board, N))
        cout << "Can black player win? Yes" << endl;
    else
        cout << "Can black player win? No" << endl;

    cout << endl;
    cout << "List of winning conditions sorted by the index of top-left stone location:" << endl;
    PrintPlayerWinCondition(num_rows, num_cols, board, N);

    // 释放动态申请的内存
    for (int i = 0; i < num_rows; i++) {
        delete[] board[i];
    }
    delete[] board;
    return 0;
}

运行方式 #

编译代码后执行命令：./生成的程序名 你的输入txt文件路径，即可得到你要求的输出结果。
