第二次修改#include<stdio.h>
           #define    NUM_BER 100
           void Piglatin(char list[]);
           int Len(char a[]);
           void Reverseb(char *a,char *b);
           void Reverse(char *first,char *second);
            int string[NUM_BER];
           int main()
           {
             
           printf("Please input a string\n");
           scanf("%s",string);
           Piglatin(string);
           printf("the result is %s\n",string);
           }
          void Piglatin(char list[])
           {
           int    index;
           int length;
           length=Len(list);
           Reverseb(&list[0],&list[length]);         
           for(index=0;index<length;index++)
           {
               Reverse(&list[index],&list[index+1]);
           }
           list[length]='a';
               list[length+1]='y';
             
          }
           int Len(char a[])
           {
           int index=0;
           while(a[index]!='\0')
           index++;
           return index;
           }
           void Reverse( char *first, char *second)
           {
               char temp;
               temp=*first;
               *first=*second;
               *second=temp;
           }
                   void Reverseb(char *a,char *b)
                   {
                       char tem;
                       tem=*a;
                           *a=*b;
                           *b=tem;
                   }


这是用来Piglatin的
