C语言编个五子棋的游戏

好的，以下是一个简单的五子棋游戏的 C 语言代码，供您参考：

#include <stdio.h>
#include <stdlib.h>
#include <stdbool.h>

#define BOARD_SIZE 15
#define BLACK 'X'
#define WHITE 'O'
#define EMPTY ' '

// 定义棋盘和当前玩家
char board[BOARD_SIZE][BOARD_SIZE];
char current_player;

// 初始化棋盘
void init_board()
{
    for (int i = 0; i < BOARD_SIZE; i++) {
        for (int j = 0; j < BOARD_SIZE; j++) {
            board[i][j] = EMPTY;
        }
    }
}

// 显示棋盘
void display_board()
{
    printf("   ");
    for (int i = 0; i < BOARD_SIZE; i++) {
        printf("%c ", i + 'A');
    }
    printf("\n");
    for (int i = 0; i < BOARD_SIZE; i++) {
        printf("%2d ", i + 1);
        for (int j = 0; j < BOARD_SIZE; j++) {
            printf("%c ", board[i][j]);
        }
        printf("\n");
    }
}

// 判断是否合法落子
bool is_valid_move(int row, int col)
{
    if (row < 0 || row >= BOARD_SIZE || col < 0 || col >= BOARD_SIZE) {
        return false;
    }
    if (board[row][col] != EMPTY) {
        return false;
    }
    return true;
}

// 判断是否胜利
bool is_win(int row, int col)
{
    char player = board[row][col];
    int count = 0;
    // 水平方向
    for (int i = col - 4; i <= col + 4; i++) {
        if (i < 0 || i >= BOARD_SIZE) {
            continue;
        }
        if (board[row][i] == player) {
            count++;
        } else {
            count = 0;
        }
        if (count == 5) {
            return true;
        }
    }
    // 垂直方向
    count = 0;
    for (int i = row - 4; i <= row + 4; i++) {
        if (i < 0 || i >= BOARD_SIZE) {
            continue;
        }
        if (board[i][col] == player) {
            count++;
        } else {
            count = 0;
        }
        if (count == 5) {
            return true;
        }
    }
    // 斜向方向
    count = 0;
    for (int i = row - 4, j = col - 4; i <= row + 4 && j <= col + 4; i++, j++) {
        if (i < 0 || i >= BOARD_SIZE || j < 0 || j >= BOARD_SIZE) {
            continue;
        }
        if (board[i][j] == player) {
            count++;
        } else {
            count = 0;
        }
        if (count == 5) {
            return true;
        }
    }
    // 反斜向方向
    count = 0;
    for (int i = row - 4, j = col + 4; i <= row + 4 && j >= col - 4; i++, j--) {
        if (i < 0 || i >= BOARD_SIZE || j < 0 || j >= BOARD_SIZE) {
            continue;
        }
        if (board[i][j] == player) {
            count++;
        } else {
            count = 0;
        }
        if (count == 5) {
            return true;
        }
    }
    return false;
}

// 交换当前玩家
void switch_player()
{
    if (current_player == BLACK) {
        current_player = WHITE;
    } else {
        current_player = BLACK;
    }
}

// 主函数
int main()
{
    int row, col;
    init_board();
    current_player = BLACK;
    while (true) {
        display_board();
        printf("当前玩家：%c，请输入落子位置（例如 A1）：", current_player);
        scanf("%d%c", &row, &col);
        col = col - 'A';
        row--;
        if (!is_valid_move(row, col)) {
            printf("非法落子，请重新输入！\n");
            continue;
        }
        board[row][col] = current_player;
        if (is_win(row, col)) {
            display_board();
            printf("游戏结束，%c 玩家获胜！\n", current_player);
            break;
        }
        switch_player();
    }
    return 0;
}

该代码实现了一个简单的五子棋游戏，玩家可以在命令行中输入落子位置，程序会自动判断是否合法，并在胜利时输出获胜玩家。
