吐血一問。 在Aix上編譯通過。 我試了一下在sco openserver 505 上編譯以下一段程序： #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); } 編譯:  cc test.c   結果老報錯，我再也不知道哪裡錯了。 高手幫助我看看。 吐血一問。 首先將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"}; 改為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中要變量的申明要在其它語句之前。 以下是修改後的語句，已在RetHat7.2下編繹通過了自已試試吧 :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); } 吐血一問。 首先將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"}; 改為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中要變量的申明要在其它語句之前。 以下是修改後的語句，已在RetHat7.2下編繹通過了自已試試吧 :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); } 吐血一問。 首先將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"}; 改為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中要變量的申明要在其它語句之前。 以下是修改後的語句，已在RetHat7.2下編繹通過了自已試試吧 :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); } 吐血一問。 只要將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"}; 放到前面定義就可以了，可以不用char *hhh[7]，效果一樣！ C++才可以隨時用變量隨時聲明/定義，C 不可以！！ [ 關閉窗口 ]
