引言：通過參考c語言庫函數(shù)qsort：

void qsort( void *base, size_t num, size_t width, int (__cdecl *compare )(const void *elem1, const void *elem2 ) );

    完成回調(diào)函數(shù)實現(xiàn)冒泡排序字符串或數(shù)字：

    代碼如下：

#include <stdio.h>#include <stdlib.h>#include <string.h>/*函數(shù)功能：以char類型交換兩個元素，大小為size，
應(yīng)用回調(diào)函數(shù)實現(xiàn)冒泡排序既能排序字符串又能排序數(shù)
。*/void swap(char *p1,char *p2,int size){    int i = 0;    char tmp = 0;    for(i = 0;i<size;i++)    {        tmp = *(p1+i);        *(p1+i) = *(p2+i);        *(p2+i) = tmp;    }}/*函數(shù)功能：比較整數(shù)的回調(diào)函數(shù)。*/int compare_int(const void *elem1,const void *elem2){    return (*(int *)elem1) - (*(int *)elem2);}/*函數(shù)功能：比較字符串的回調(diào)函數(shù)。*/int compare_str(const void *elem1,const void *elem2){    return strcmp((char *)(*(int *)elem1), (char *)(*(int *)elem2));}/*函數(shù)功能：冒泡排序函數(shù)。*/void bubble_str_int(void *base,int size,int width,int ( *cmp )(const void *elem1, const void *elem2 )){    int i = 0;    int j = 0;    for(i = 0;i<size-1;i++)    {        for(j = 0;j<size-i-1;j++)        {            if(cmp(((char *)base+(j*width)),((char *)base+(j+1)*width))<0)            {                swap((char *)base+(j*width),(char *)base+(j+1)*width,width);            }        }    }}int main(){    char *arr_str[] = {"ddddd","aaaaa","ccccc","bbbbb","zzzzz"};    int arr_int[] = {1,3,5,7,9,2,4,6,8,10};     int i = 0;    int size_int = sizeof(arr_int)/sizeof(arr_int[0]);    int size_str = sizeof(arr_str)/sizeof(arr_str[0]);    bubble_str_int(arr_int,size_int,sizeof(arr_int[0]),compare_int);    printf("bubble_sort int:\n");    for(i = 0;i<size_int;i++)    {        printf("%d ",arr_int[i]);    }    printf("\n");    bubble_str_int(arr_str,size_str,sizeof(arr_str[0]),compare_str);    printf("bubble_sort string:\n");    for(i = 0;i<size_str;i++)    {        printf("%s\n",arr_str[i]);    }    system("pause");    return 0;}
