494 - Kindergarten Counting Game

很水的，但WA了两次。太粗心了。忘了标点分隔单词了……

#include<stdio.h>
#include<ctype.h>
int main(void)
{
 char ch;
 ch = getchar();
 do{
  int count = 0,label = 0;
  while(ch != '/n')
  {
   if(label == 0&& isalpha((int)ch))
   {
    count++;
    label = 1;
   }
   if( !isalpha((int)ch))
    label = 0;
   ch = getchar();
  }
  printf("%d/n",count);
  ch = getchar();
 }while ((int)ch != EOF);
 return 0;
}
