一个口令程序，结果有二十多个错误，求高人看看
#include<stdio.h>#include<conio.h>
#include<dos.h>
int main(void)
{
struct date today;
struct time now;
getdate(&today);//把系统当前日期存入today所指向的date结构中
gettime(&now);//把系统当前时间存入today所指向的time结构中
//设定字符颜色和背景
textcolor(LIGHTGREEN);
textbackground(BLUE);
//但输入口令不对时，反复进行以下循环
do{
clrscr();
gotoxy(25,10);
printf("Today's date is %d-%d-%d\n".today,da_year,today.da_mon,today.da_day);
gotoxy(28,12);
printf("the time is %02d:%02d:%02d\n",now.ti_hour,now.ti_min,now.ti_sec);
gotoxy(1,1);
printf("please iput password:");
}while(atoi((char *)getpass("password:"))!=today.da_mon+now.ti_hour);
//如果输入正确，则显示正确信息并退出
textcolor(WHITE);
textbackground(BLACK);
clrscr();
gotoxy(1,1);
printf("PASSWORD CORRECT!!\n);
printf("PRESS ANY KEY TO QUIT.\n);
getchar();
}
