关于continue的用法疑问：
// animal.c
#include
#include
int main(void)
{
char ch;
printf(" Give me a letter of the alphabet,and i will give ");
printf(" an animal name \n beginning with that letter.\n");
printf("Please type in a letter :type # to end my act.\n");
while((ch= getchar()) = '#');
{
if('\n'==ch)
continue;
if(islower(ch))
switch(ch)
{
case 'a':
printf("argali,awild sheep of Asia\n");
break;
case 'b':
printf("bablirusa,a wild pig of Malay \n");
break;
case 'c':
printf("coati,racoonlike mammal \n");

printf("Desman,aquatic,molelike critter \n");
break;
case 'e':
printf("echidna,the spiny anteater\n");
break;
case'f':
printf("fisher,brownish marten \n");
break;

printf("That's a stumper \n");
}
else
printf("I recognize only lowercase letters.\n");
while(getchar()!='\n')
continue;
printf("Please enter another letter of a #.\n");
}
printf("Bye!\n");
return 0;
}
编译了一下,发现有问题：

Answer 1

你的while后面有个分号.后面那个大括号就不在while里了,所以continue也不再while里,continue只有在循环内才有意义,否则就会出现这种错误.
