c语言写一个五子棋游戏

好的，以下是一个简单的五子棋游戏的 C 代码实现：

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

#define ROW 15
#define COL 15

char board[ROW][COL];   // 棋盘
char player1 = 'X';     // 玩家1棋子
char player2 = 'O';     // 玩家2棋子

// 初始化棋盘
void init_board() {
    int i, j;
    for (i = 0; i < ROW; i++) {
        for (j = 0; j < COL; j++) {
            board[i][j] = '+';
        }
    }
}

// 打印棋盘
void print_board() {
    int i, j;
    for (i = 0; i < ROW; i++) {
        for (j = 0; j < COL; j++) {
            printf("%c ", board[i][j]);
        }
        printf("\n");
    }
}

// 下棋
void play(char player) {
    int x, y;
    printf("%c's turn, please enter the coordinate(x y): ", player);
    scanf("%d %d", &x, &y);
    if (x < 0 || x >= ROW || y < 0 || y >= COL) {
        printf("The coordinate is invalid!\n");
        play(player);
        return;
    }
    if (board[x][y] != '+') {
        printf("The coordinate has been occupied!\n");
        play(player);
        return;
    }
    board[x][y] = player;
}

// 判断是否胜利
int check_win(char player) {
    int i, j, count;
    // 检查行
    for (i = 0; i < ROW; i++) {
        count = 0;
        for (j = 0; j < COL; j++) {
            if (board[i][j] == player) {
                count++;
                if (count == 5) {
                    return 1;
                }
            } else {
                count = 0;
            }
        }
    }
    // 检查列
    for (j = 0; j < COL; j++) {
        count = 0;
        for (i = 0; i < ROW; i++) {
            if (board[i][j] == player) {
                count++;
                if (count == 5) {
                    return 1;
                }
            } else {
                count = 0;
            }
        }
    }
    // 检查左斜线
    for (i = 0; i < ROW - 4; i++) {
        for (j = 0; j < COL - 4; j++) {
            if (board[i][j] == player && board[i+1][j+1] == player && board[i+2][j+2] == player && board[i+3][j+3] == player && board[i+4][j+4] == player) {
                return 1;
            }
        }
    }
    // 检查右斜线
    for (i = 0; i < ROW - 4; i++) {
        for (j = 4; j < COL; j++) {
            if (board[i][j] == player && board[i+1][j-1] == player && board[i+2][j-2] == player && board[i+3][j-3] == player && board[i+4][j-4] == player) {
                return 1;
            }
        }
    }
    return 0;
}

int main() {
    int round = 0;
    init_board();
    print_board();
    while (1) {
        if (round % 2 == 0) {
            play(player1);
        } else {
            play(player2);
        }
        print_board();
        if (check_win(player1)) {
            printf("%c win!\n", player1);
            break;
        }
        if (check_win(player2)) {
            printf("%c win!\n", player2);
            break;
        }
        if (round == ROW * COL) {
            printf("Tie!\n");
            break;
        }
        round++;
    }
    return 0;
}

这个程序会在控制台上显示一个 15x15 的棋盘，玩家可以输入坐标下棋，程序会不断检查是否有一方胜利或者平局。
