#include "string.h"
#include "stdio.h"



sort (char *a[],int n)
{ int i,j;
char *p;

for(i=0;i<=n-1;i++)
 if(strcmp(a[i],a[i+1])>0)
 {p=a[i];
 a[i]=a[i+1];
 a[i+1]=p;
 }
}
main()
{ int i;
char *book []={"jhfgjhgj","hgffjn","tyui","dfgh","bnmvcx","lokjiuh"};
sort(book,6);
for(i=0;i<6;i++)
printf("%s\n",book[i]);
}
原功能为把字符串从小到大输出，没反应

#include "string.h"
#include "stdio.h"
main()
{
    int i;
    char *p;
    char *book[]={"jhfgjhgj","hgffjn","tyui","dfgh","bnmvcx","lokjiuh"};
    for(i=0;i<=6-1;i++)
        if((strcmp(book[i],book[i+1]))>0)
        {
            p=book[i];
            book[i]=book[i+1];
            book[i+1]=p;
        }
    for(i=0;i<6;i++)
        printf("%s\n",book[i]);
}



函数里你只是改变地址   起不到效果，直接在main() 函数里操作就好
