生成一个简单的c语言五子棋对战代码

好的，这是一个简单的 C 语言五子棋对战代码，希望能帮助到你：

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

#define ROWS 15
#define COLS 15
#define BLANK ' '
#define PLAYER 'X'
#define COMPUTER 'O'

char chessboard[ROWS][COLS]; // 棋盘
int player_row, player_col; // 玩家下棋的行列坐标
int computer_row, computer_col; // 电脑下棋的行列坐标

// 初始化棋盘
void init_chessboard() {
    int i, j;
    for (i = 0; i < ROWS; i++) {
        for (j = 0; j < COLS; j++) {
            chessboard[i][j] = BLANK;
        }
    }
}

// 显示棋盘
void display_chessboard() {
    int i, j;
    printf("  ");
    for (i = 0; i < ROWS; i++) {
        printf("%d ", i + 1);
    }
    printf("\n");
    for (i = 0; i < ROWS; i++) {
        printf("%d ", i + 1);
        for (j = 0; j < COLS; j++) {
            printf("%c ", chessboard[i][j]);
        }
        printf("\n");
    }
}

// 判断落子是否合法
int is_valid(int row, int col) {

    }

// 检查是否获胜

                    return 1;
                }
                if (i + 4 < ROWS && chessboard[i + 1][j] == c && chessboard[i + 2][j] == c && chessboard[i + 3][j] == c && chessboard[i + 4][j] == c) {

                }
                if (j - 4 >= 0 && i + 4 < ROWS && chessboard[i + 1][j - 1] == c && chessboard[i + 2][j - 2] == c && chessboard[i + 3][j - 3] == c && chessboard[i + 4][j - 4] == c) {
                    return 1;
                }
            }
        }
    }
    return 0;
}

// 判断游戏是否结束
int is_gameover() {
    if (check_win(PLAYER)) {
        printf("恭喜您，获胜了！\n");
        return 1;
    }
    if (check_win(COMPUTER)) {
        printf("很遗憾，您输了！\n");
        return 1;
    }
    int i, j;
    for (i = 0; i < ROWS; i++) {
        for (j = 0; j < COLS; j++) {
            if (chessboard[i][j] == BLANK) {
                return 0;
            }
        }
    }
    printf("平局！\n");
    return 1;
}

int main() {
    srand(time(0));
    init_chessboard();
    display_chessboard();
    while (!is_gameover()) {
        player_move();
        display_chessboard();
        if (!is_gameover()) {
            computer_move();
            display_chessboard();
        }
    }
    return 0;
}

这个程序实现了人机对战，玩家执黑先行，输入行列坐标下棋，电脑执白后行，采用简单的 AI 算法进行下棋，直到出现获胜或平局为止。
