使用c语言编写一、设计游戏:五子棋; 要求:1、显示11*11的棋盘界面; (25分〉 2、两位选手能按照行棋规则落子（分别为黑白色); (25分) 3、能够判断棋局的胜负情况，并显示对弈结果; (25分) 4、背景音乐和落子音效，且能提供设置界面开启和关闭该功能;(20分>5、其他功能。

以下是一个使用 C 语言编写的五子棋游戏示例代码，基于控制台输出实现：

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

#define BOARD_SIZE 11
#define BLACK 'X'
#define WHITE 'O'

char board[BOARD_SIZE][BOARD_SIZE];

void init_board() {
    for (int i = 0; i < BOARD_SIZE; i++) {
        for (int j = 0; j < BOARD_SIZE; j++) {
            board[i][j] = '+';
        }
    }
}

void print_board() {
    system("cls");
    printf("      ");
    for (int i = 0; i < BOARD_SIZE; i++) {
        printf("%2d ", i);
    }
    printf("\n");
    for (int i = 0; i < BOARD_SIZE; i++) {
        printf("%4d ", i);
        for (int j = 0; j < BOARD_SIZE; j++) {
            printf("%2c ", board[i][j]);
        }
        printf("\n");
    }
}

bool check_win(char player) {
    // 检查行
    for (int i = 0; i < BOARD_SIZE; i++) {
        for (int j = 0; j < BOARD_SIZE - 4; j++) {
            if (board[i][j] == player && board[i][j+1] == player && board[i][j+2] == player && board[i][j+3] == player && board[i][j+4] == player) {
                return true;
            }
        }
    }
    // 检查列
    for (int i = 0; i < BOARD_SIZE - 4; i++) {
        for (int j = 0; j < BOARD_SIZE; j++) {
            if (board[i][j] == player && board[i+1][j] == player && board[i+2][j] == player && board[i+3][j] == player && board[i+4][j] == player) {
                return true;
            }
        }
    }
    // 检查正斜线
    for (int i = 0; i < BOARD_SIZE - 4; i++) {
        for (int j = 0; j < BOARD_SIZE - 4; j++) {
            if (board[i][j] == 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 true;
            }
        }
    }
    // 检查反斜线
    for (int i = 0; i < BOARD_SIZE - 4; i++) {
        for (int j = 4; j < BOARD_SIZE; 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 true;
            }
        }
    }
    return false;
}

bool place_piece(char player, int row, int col) {
    if (board[row][col] != '+') {
        return false;
    }
    board[row][col] = player;
    return true;
}

void play_game() {
    int row, col;
    char player = BLACK;
    bool game_over = false;
    while (!game_over) {
        print_board();
        printf("Player %c's turn. Please enter row and column: ", player);
        scanf("%d %d", &row, &col);
        if (row < 0 || row >= BOARD_SIZE || col < 0 || col >= BOARD_SIZE) {
            printf("Invalid row or column. Please try again.\n");
            continue;
        }
        if (!place_piece(player, row, col)) {
            printf("The position is already occupied. Please try again.\n");
            continue;
        }
        if (check_win(player)) {
            printf("Player %c wins!\n", player);
            game_over = true;
        }
        player = player == BLACK ? WHITE : BLACK;
    }
}

int main() {
    init_board();
    play_game();
    return 0;
}

该代码实现了棋盘的初始化、输出、棋子的落子和胜利判断等功能。玩家可以通过控制台输入行和列来落子，当有一方连成五子时，游戏结束并显示胜利者。
