用C语言写一个五子棋游戏的代码

编写一个完整的五子棋游戏的C语言代码需要相当多的篇幅，这里我会给出一个简单的框架以及关键部分的代码示例，供你参考和继续扩展：

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

typedef struct {
    int row;
    int col;
} Point;

// 棋盘大小
#define BOARD_SIZE 15

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

// 标记玩家1和玩家2的棋子
enum Player {PLAYER_X = 'X', PLAYER_O = 'O'};
Player currentPlayer = PLAYER_X; 

void printBoard() {
    for (int i = 0; i < BOARD_SIZE; i++) {
        printf("%s", board[i]);
        if (i % 5 == 4) printf("\n");
    }
}

bool isValidMove(int row, int col) {
    return row >= 0 && row < BOARD_SIZE && col >= 0 && col < BOARD_SIZE && board[row][col] == '\0';
}

// 玩家下棋函数
void makeMove(int row, int col) {
    board[row][col] = currentPlayer;
}

// 判断是否形成五子连珠
bool checkWin(int player) {
    // 这里仅给出判断一行、一列和对角线的简单示例，实际游戏中还需遍历更多方向
    for (int i = 0; i < BOARD_SIZE; i++) {
        if (board[i][0] != '\0' && board[i][0] == player && board[i][1] == player && board[i][2] == player &&
            board[i][3] == player && board[i][4] == player) {
            return true;
        }
        if (board[0][i] != '\0' && board[0][i] == player && board[1][i] == player && board[2][i] == player &&
            board[3][i] == player && board[4][i] == player) {
            return true;
        }
    }
    return false;
}

int main() {
    initBoard(); // 初始化棋盘
    while (!checkWin(PLAYER_X) && !checkWin(PLAYER_O)) {
        printBoard();
        int row, col;
        printf("Player %c's turn. Enter row and column (0-14): ", currentPlayer == PLAYER_X ? 'X' : 'O');
        scanf("%d%d", &row, &col);
        if (isValidMove(row, col)) {
            makeMove(row, col);
            currentPlayer = currentPlayer == PLAYER_X ? PLAYER_O : PLAYER_X;
        } else {
            printf("Invalid move. Try again.\n");
        }
    }
    printBoard();
    return 0;
}
