上面这是不ac 的代码，我写的排序绝对是没有问题，不知道为什么这道题用fgets读取就会WA 求大神指教，下面这个getchar就ac了

#include<stdio.h>#include<string.h>#include<stdlib.h>#include<ctype.h>char word[100010][50] = {'\0'};int cmp( const void *s1, const void *s2 )  {          return strcmp( (char*)s1, (char*)s2 );  };  int main(){    char ch;    int n = 0, len = 0;    while( 1)    {        if( (ch = getchar()) == EOF) break;        if( isalpha( ch) )            word[n][len ++] = tolower(ch);        else            if( isalpha( word[n][0])) {                word[n ++][len] = '\0';                len = 0;            }    }    qsort( word, n, sizeof (word[0]), cmp);    for( int i = 0; i < n; i ++)        if( strcmp( word[i], word[i + 1]))            printf( "%s\n", word[i]);    return 0;}
