Thread: String deletion problem

I have write a programme in order to do such a job:
if you input a string like "abc**d", it will delete the charactors in front of the stars (and the number of stars are equal to the number of charactors will be deleted), so it will return back the string as "ad".
if the stars are in front of the charactors, the programme will eliminate them, (e.g. input "***ab" will still return "ab")
but my programme had a problem, the charactors behind the stars will not insert into the list..and will not print on the screen consequently. I check it for many times and it seems no problem. could anyone do me a favor? Thx very much..

Here's my programme:

Code:

#include <stdio.h>
#include "list.h"
#include "fatal.h"
#define SIZE 10
void
PrintList( const List L )
{
  Position P = Header( L );
  if(IsEmpty(L))
    printf( "Empty list\n" );
  else
    {
      do
        {
	  P = Advance( P );
	  printf( "%c", Retrieve( P ) );
        } while( !IsLast( P, L ) );
      printf( "\n" );
    }
}

int
main(void)
{
  List L;
  Position P;
  int i = 0, n, m, counter = 0;
  char c[SIZE];
  L = MakeEmpty( NULL );
  P = Header( L );
  printf("Enter a string:");
  scanf("%s", c);
  do 
    {
      if(c[i] == '*')
	{
	  i++;
	}
    } while (c[i] == '*');
  do
    {
      do
	{
	  if (c[i] == '*')
	    {
	      if (IsEmpty(L) != 1)
		{
		  m = n - 1;
		  if (counter == 0)
		    m = i - 1;
		  Delete(c[m], L);
		  n = m;
		  i++;
		  counter++;
		}
	      if (IsEmpty(L) == 1)
		i++;
	    }
	}while (c[i] == '*');
      if (c[i] != '*')
	{
	  Insert(c[i], L, P);
	  P = Advance(P);
	  i++;
	}
    }while (c[i] != '\0');
  PrintList(L);
  return(0);
}

The attach file list.c is the list implementation file, just copy from the textbook, no problem at all..
