tai1688,    我把你sort的部分改為如下

void sort(person Person[],int a)
{
     person temp;
     int j=0,c=1;
     for(int i=0;i0){
                           temp=Person[i];
                           Person[i]=Person[j];
                           Person[j]=temp;
                           }
                   } 
                   c  ;
             }
}
