这是一道指针题,模拟一个数字式时钟.可为什么不通,我找不到原因,请高手帮助.

#include"stdio.h"
struct clock
{
int hour;
int minute;
int second;
};
typedef struct lock CLOCK;
void update (CLOCK *t)
{
t->second++;
if(t->second==60)
{
t->second=0;
t->minute++;
}
if(t->minute==60)
{
t->minte=0;
t->hour++;
}
if(t->hour==24)
t->hour=0;
}
void display(CLOCK *t)
{
printf("*%d:%d:%d\r",t->hour,t->minute,t-.second);
}
void deplay()
{
int t;
for(t=0;t<10000;t++);
}
main()
{
int i;
CLOCK *time;
time->hour=time-?minute=time->second=0;
for(i=0;i<10000;i++)
{
update(time);
display(time);
delay(0;
}
}

式格有点乱,还有这种写法吗？time-&gt;hour=time-?minute=time-&gt;second=0;

#include"stdio.h"
struct clock
{
int hour;
int minute;
int second;
};
typedef struct clock CLOCK;
void update (CLOCK *t)
{
t->second++;
if(t->second==60)
{
t->second=0;
t->minute++;
}
if(t->minute==60)
{
t->minute=0;
t->hour++;
}
if(t->hour==24)
t->hour=0;
}
void display(CLOCK *t)
{
printf("%02d:%02d:%02d\r",t->hour,t->minute,t->second);
}
void deplay()
{
int t;
for(t=0;t<10000;t++);
}
main()
{
CLOCK a;
CLOCK *time=&a;
time->hour=time->minute=time->second=0;
for(;;)
{
update(time);
display(time);
deplay();
}
}

.....LS的那是啥？变的也太快了吧

#include"stdio.h"
struct clock
{
int hour;
int minute;
int second;
};
typedef struct clock CLOCK;
void update (CLOCK *t)
{
t->second++;
if(t->second==60)
{
t->second=0;
t->minute++;
}
if(t->minute==60)
{
t->minute=0;
t->hour++;
}
if(t->hour==24)
t->hour=0;
}
void display(CLOCK *t)
{
printf("%02d:%02d:%02d\r",t->hour,t->minute,t->second);
}
void deplay()
{
int t;
for(t=0;t<10000;t++);
}
main()
{
CLOCK a;
CLOCK *time=&a;
time->hour=time->minute=time->second=0;
for(;;)
{
update(time);
display(time);
deplay();
}
}
为什么到23秒就重新记数；

感谢诸位高手的帮助.
