用c语言写一个六子棋的代码

以下是一个简单的 C 语言六子棋游戏的代码，仅供参考：

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

#define BOARD_SIZE 6 // 棋盘大小

char board[BOARD_SIZE][BOARD_SIZE]; // 棋盘

// 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] = '.';
        }
    }
}

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

// 判断是否胜利
bool is_win(char c) {
    // 判断列
    for (int i = 0; i < BOARD_SIZE; i++) {
        int count = 0;
        for (int j = 0; j < BOARD_SIZE; j++) {
            if (board[j][i] == c) {
                count++;
                if (count >= 4) {
                    return true;
                }
            } else {
                count = 0;
            }
        }
    }
    // 判断行
    for (int i = 0; i < BOARD_SIZE; i++) {
        int count = 0;
        for (int j = 0; j < BOARD_SIZE; j++) {
            if (board[i][j] == c) {
                count++;
                if (count >= 4) {
                    return true;
                }
            } else {
                count = 0;
            }
        }
    }
    // 判断正斜线
    for (int i = 0; i <= BOARD_SIZE - 4; i++) {
        for (int j = 0; j <= BOARD_SIZE - 4; j++) {
            if (board[i][j] == c && board[i+1][j+1] == c &&
                board[i+2][j+2] == c && board[i+3][j+3] == c) {
                return true;
            }
        }
    }
    // 判断反斜线
    for (int i = 0; i <= BOARD_SIZE - 4; i++) {
        for (int j = BOARD_SIZE - 1; j >= 3; j--) {
            if (board[i][j] == c && board[i+1][j-1] == c &&
                board[i+2][j-2] == c && board[i+3][j-3] == c) {
                return true;
            }
        }
    }
    return false;
}

// 下棋
bool play(int x, int y, char c) {
    if (board[x][y] != '.') {
        return false;
    }
    board[x][y] = c;
    return true;
}

int main() {
    init_board();
    print_board();
    char player1 = 'X';
    char player2 = 'O';
    int x, y;
    char current_player = player1;
    while (true) {
        printf("Player %c's turn.\n", current_player);
        printf("Enter row and column (e.g. 1 2): ");
        scanf("%d %d", &x, &y);
        if (play(x-1, y-1, current_player)) {
            print_board();
            if (is_win(current_player)) {
                printf("Player %c wins!\n", current_player);
                break;
            }
            if (current_player == player1) {
                current_player = player2;
            } else {
                current_player = player1;
            }
        } else {
            printf("Invalid move, try again.\n");
        }
    }
    return 0;
}

该代码实现了一个简单的六子棋游戏，包括初始化棋盘，显示棋盘，下棋，判断胜利等功能。玩家可以通过输入行和列来下棋，程序会判断该位置是否可下，如果可下，则将该位置赋为当前玩家的棋子，并检查当前玩家是否胜利。如果胜利，则输出胜利信息并结束游戏。如果当前玩家不是胜利者，则交换玩家并继续游戏。
