你用 08xx 會讓 compiler 以為你要用 octal value. 應該是要做 type cast 的。
我忘了怎么做 type cast. 去找找吧。

  else if(dob>=0421&&dob<=0520)
   printf("Your Western Zodiac Sign is Taurus.\n");

把所有的"0321"，“0420”前面的'0'丢掉就可以了。
我有点意见，如果我特地打我的生日是“0499“呢？

你忘了打"）"在";"的前面，
应该是。。。。birth (01-31): "）;
然后把while(key!='E');
换成while(key!='E'||key!='e')看看可以吗？刚才我试了，没有问题。

不知道那里出了问题
它的output竟然是这样的：
Please enter your day of birth (1-31): 1
Please enter your month of birth (1-12): 2
Your Western Zodiac Sign is Aquarius.
Enter any key to continue or E to exit.
Please enter your day of birth (1-31):

总觉得这coding很多缺陷~
大家帮帮忙。。。
拜托了~

Please enter your day of birth: 20
Please enter your month of birth: 4
Your Western Zodiac Sign is Taurus.
Press any key to continue or e to exit: w

Please enter your day of birth: 33
Please enter your month of birth: 20
Wrong day or month.
Press any key to continue or e to exit: e

Press any key to continue_


基本上是没问题了
可是我在想要怎么让显示成以下这样呢？


Please enter your day of birth: 33
Wrong day.
Press any key to continue or e to exit: w

Please enter your day of birth: 3
Please enter your month of birth: 33
Wrong month.
Press any key to continue or e to exit: w

Please enter your day of birth: 20
Please enter your month of birth: 4
Your Western Zodiac Sign is Taurus.
Press any key to continue or e to exit: e

Press any key to continue_

试下这样
else(
if(day>31)
printf(“wrong date”);
else if (month>12)
printf("wrong month");
)
