给所有给出的字符串排字典序。。。。数组记得要开大些，，题目说5000行，但并不代表只有5000个单词。。。

#include<stdio.h>#include<string.h>#include<ctype.h>#include<stdlib.h>char s[5005 * 205][205];int compare(const void *a, const void *b){return strcmp((char *)a, (char *)b);}int main(){int i = 0, j = 0;char ch;while ((ch = getchar()) != EOF){if (isalpha(ch))s[i][j++] = tolower(ch);if (!isalpha(ch) && isalpha(s[i][0])){s[i++][j] = '\0';j = 0;}}qsort(s, i, sizeof(char)*205, compare);for(j = 1, puts(s[0]);j < i; j++)if(strcmp(s[j - 1], s[j]))puts(s[j]);return 0;}
