任务
用C语言设计一个井字棋游戏,包含以下内容：
1.用结构体设计一个可以创建账户名称，密码累积输赢数字且账户相关信息能够存储在数据文件中，并由程序访问
2.设计一个3*3井字棋游戏，包括游戏开始菜单设计，棋盘的生成与初始化与棋盘打印，玩家下棋和电脑下棋，判断输赢和统计输赢次数，且在开始游戏后可以选择玩家先手或电脑先手
本人写了一段C语言代码，但是代码无法运行，求各位帮我看看我的程序的问题在哪以及如何改正，以及创建账户和密码和统计输赢次数的部分如何实现？
本人代码如下：

#include<stdlib.h>

exit(0);
}
}
}
void registers()
{
users c,d;
FILE *fp;
char temp[20];
int count = 0;
printf("Welcome to the registration screen!\n");
Sleep(1000);
fp = fopen("users.txt","r");
fread(&d, sizeof(struct The_users), 1, fp);
printf("Please enter your account number\n");
scanf("%s",&c.id);
while (1)
{
if (strcmp(c.id, d.id))
{
