qsort对数组字符串/结构体字符串排序

百度找了好久都不能 最后问的学姐  解决啦  谢谢任真学姐啦#include <stdio.h>#include <stdlib.h>#include <string.h>int cmp(const void *a,const void *b){return strcmp((char *)a,(char *)b);}int main(){int i;char a[5][10]={"abcd","abc","abcde","feag","fdag"};qsort(a,5,sizeof(a[0]),cmp);for(i=0;i<5;i++)puts(a[i]);return 0;}

对结构体字符串排序

#include <stdio.h>#include <stdlib.h>#include <string.h>struct node{char w[11],d[11];}dic[100005];int cmp(const void *a,const void *b){return strcmp((*(node *)a).d,(*(node *)b).d);}int main(){int i=0,j;char ch;while(1){scanf("%s %s",dic[i].d,dic[i].w);getchar(),ch=getchar();i++;if(ch=='\n')break;}qsort(dic,i,sizeof(node),cmp);for(j=0;j<i;j++)printf("%s\n",dic[j].d);}
