摘要：
一、对int类型数组排序int num[100];Sample:int cmp ( const void *a , const void *b ){return *(int *)a - *(int *)b;}qsort(num,100,sizeof(num[0]),cmp);二、对char类型数组排序（同int类型）char word[100];Sample:int cmp( const void *a , const void *b ){return *(char *)a - *(int *)b;}qsort(word,100,sizeof(word[0]),cmp);三、对double类型 阅读全文
