吐血一问。

在Aix上编译通过。
我试了一下在sco openserver 505 上编译以下一段程序：

#include<stdio.h>;
#include<time.h>;
#include<sys/timeb.h>;
main()
{
time_t t;
struct tm tt;
char mytime[11];
char mysun[7];
time(&t);
localtime_r(&t,&tt);
char hhh[7][7] = {"星期天","星期一","星期二","星期三","星期四","星期五", "星期六"};
sprintf(mysun,"%s",hhh[(tt.tm_wday)]);
sprintf(mytime,"%d%d%d",tt.tm_year+1900,tt.tm_mon,tt.tm_mday);
printf("%s\n",mysun);
printf("%s\n",mytime);


}

编译:  cc test.c  

结果老报错，我再也不知道哪里错了。

高手帮助我看看。

首先将char hhh[7][7]={"星期天","星期一","星期二","星期三","星期四","星期五", "星期六"};
改为char *hhh[7]={"星期天","星期一","星期二","星期三","星期四","星期五", "星期六"};

第二，在C中要变量的申明要在其它语句之前。

以下是修改后的语句，已在RetHat7.2下编绎通过了自已试试吧 :wink:

#include<stdio.h>;
#include<time.h>;
#include<sys/timeb.h>;
main()
{
time_t t;
struct tm tt;
char mytime[11];
char mysun[7];
char *hhh[7]={"星期天","星期一","星期二","星期三","星期四","星期五", "星期六"};
time(&t);
localtime_r(&t,&tt);
sprintf(mysun,"%s",hhh[(tt.tm_wday)]);
sprintf(mytime,"%d%d%d",tt.tm_year+1900,tt.tm_mon,tt.tm_mday);
printf("%s\n",mysun);
printf("%s\n",mytime);

}

只要将char hhh[7][7] = {"星期天","星期一","星期二","星期三","星期四","星期五", "星期六"}; 放到前面定义就可以了，可以不用char *hhh[7]，效果一样！

C++才可以随时用变量随时声明/定义，C 不可以！！
