模块化编程——五子棋游戏

关于下棋后无法打印棋盘的问题

代码如下：
main.c

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include "include\game.h"
#define SIZE 15

int main()
{
    int input = 0;
    do
    {
        srand((unsigned int)time(NULL));
        menu();
        printf("请选择(1—play/0—exit):>");
        scanf("%d", &input);
        switch (input)
        { 
        case 1:
            printf("五子棋游戏\n");
            game();
            break;
        case 0:
            printf("退出游戏\n");
            break;
        default:
            printf("输入错误,重新输入\n");
            break;
        }
    } while (input);
    return 0;
}

game.h

```c
#ifndef _GAME_H
#define _GAME_H
void menu();
void game();
void init_game();
void draw_board();
int check_pos(int x, int y);
int check_line(int x, int y, int dx, int dy);
int check_win();
void game_loop();


#endif

这是项目里的情况

resouce文件夹里是空的

如果有知道请帮忙发一下修改后的源码。

把定义为全局变量的x和y改为局部变量，你的x和y定义的全局变量，下面好多函数又对x和y进行赋值，程序会死在check_win() 这个函数上，这个函数出现死循环。

改完之后的结果：

我只改了你说的无法打印棋盘问题，其他的还没看检查。

谢谢，感谢大佬的解答!
