用C语言编写五子棋游戏，给出代码

以下是一个简单的五子棋游戏的示例代码：

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

#define SIZE 15

char board[SIZE][SIZE];

// 初始化棋盘
void initBoard() {
    for (int i = 0; i < SIZE; i++) {
        for (int j = 0; j < SIZE; j++) {
            board[i][j] = '-';
        }
    }
}

// 绘制棋盘
void drawBoard() {
    for (int i = 0; i < SIZE; i++) {
        for (int j = 0; j < SIZE; j++) {
            printf("%c ", board[i][j]);
        }
        printf("\n");
    }
}

// 检查是否有五子连线
bool checkWin(int row, int col, char player) {
    int count = 1;
    
    // 水平方向
    for (int i = col - 1; i >= 0 && board[row][i] == player; i--) {
        count++;
    }
    for (int i = col + 1; i < SIZE && board[row][i] == player; i++) {
        count++;
    }
    if (count >= 5) {
        return true;
    }
    
    // 垂直方向
    count = 1;
    for (int i = row - 1; i >= 0 && board[i][col] == player; i--) {
        count++;
    }
    for (int i = row + 1; i < SIZE && board[i][col] == player; i++) {
        count++;
    }
    if (count >= 5) {
        return true;
    }
    
    // 左斜方向
    count = 1;
    for (int i = row - 1, j = col - 1; i >= 0 && j >= 0 && board[i][j] == player; i--, j--) {
        count++;
    }
    for (int i = row + 1, j = col + 1; i < SIZE && j < SIZE && board[i][j] == player; i++, j++) {
        count++;
    }
    if (count >= 5) {
        return true;
    }
    
    // 右斜方向
    count = 1;
    for (int i = row - 1, j = col + 1; i >= 0 && j < SIZE && board[i][j] == player; i--, j++) {
        count++;
    }
    for (int i = row + 1, j = col - 1; i < SIZE && j >= 0 && board[i][j] == player; i++, j--) {
        count++;
    }
    if (count >= 5) {
        return true;
    }
    
    return false;
}

int main() {
    initBoard();
    int row, col;
    char player = 'X';
    
    while (true) {
        drawBoard();
        
        printf("Player %c's turn. Enter row and column: ", player);
        scanf("%d %d", &row, &col);
        
        if (row < 0 || row >= SIZE || col < 0 || col >= SIZE || board[row][col] != '-') {
            printf("Invalid move. Try again.\n");
            continue;
        }
        
        board[row][col] = player;
        
        if (checkWin(row, col, player)) {
            printf("Player %c wins!\n", player);
            break;
        }
        
        // 切换玩家
        player = (player == 'X') ? 'O' : 'X';
    }
    
    drawBoard();
    
    return 0;
}

这段代码实现了一个简单的五子棋游戏。玩家可以依次输入行号和列号来下棋，程序会判断是否有五子连线来决定胜负。注意，这只是一个简单的示例，还可以进一步完善游戏规则和用户交互体验。希望对您有帮助！
