char array 是不能直接 assign string 的，你必须使用 strcpy()。

warning C4700: local variable 'availability' used without having been initialized

我试着去debug它
结果error反而更多。。

onlylonly

scanf("%c",availability);

应该是

scanf("%c",&availability);

你要让scanf指导储存的地方的地址是什么， 说以必须用address operator &。

output不对耶~
看不出code有什么问题。。。
output如下：

  Enter id number for a HORROR dvd: 123abc
  Enter title for a HORROR dvd:  Spiderman
  Enter duration for a HORROR dvd in hours:  3
  Enter duration for a HORROR dvd in minutes:  15
  Enter classification for a HORROR dvd:    Enter availability for a HORROR dvd:
  Enter T for TRUE or enter F for FALSE:   

cheng1986

classification 被 skip 掉了
應該是 input buffer 的問題
參考: http://www.gidnetwork.com/b-60.html

solidx

just add this: getchar(); after each scanf to remove the enter key feed.

请问这是怎么一回事呢？

cheng1986

input buffer的問題..
建議自己另外寫讀取value然後clear buffer的function
例如
char readChar() {
   char c = ' ';
   scanf("%c", &c);
   while(getchar() != '\n');
   return c;
}
