Thread: for loop

hello guys,
I'm trying to do a shape of star.
I have to do print line 1-4 again in lines 6-9.
Total 9 lines.

// line 6 same like line 4
// line 7 same like line 3
// line 8 same like line 2
// line 9 same like line 1


Can anyone tell me how to do it without back every line again.

Here's the link to my code :

Thanks a lot

Code:

#include <stdio.h>

int
main ()
{
  int s, i, j;

  // for star
  printf ("Enter size (10-20)\n");
  scanf (" %d", &s);
  for (i = 1; i < 2; i++)
    {
      for (j = 1; j <= 2 * s - 1; j++)
	{
	  if (j == s)
	    printf ("o");
	  else
	    printf ("-");

	}
      printf ("\n");
    }
  for (i = 2; i < 3; i++)
    {
      for (j = 1; j <= 2 * s - 1; j++)
	{
	  if (j == s + 1 || j == s - 1)
	    printf ("o");
	  else
	    printf ("-");
	}
      printf ("\n");
    }
  for (i = 3; i < 4; i++)
    {
      for (j = 1; j <= 2 * s - 1; j++)
	{
	  printf ("o");
	}
      printf ("\n");
    }

  for (i = 4; i < 5; i++)
    {
      for (j = 1; j <= 2 * s - 1; j++)
	{
	  if (j == 2 * s - 2 || j == 2)
	    printf ("o");
	  else
	    printf ("-");
	}
      printf ("\n");
    }
  for (i = 5; i < 6; i++)
    {
      for (j = 1; j <= 2 * s - 1; j++)
	{
	  if (j == 2 * s - 3 || j == 3)
	    printf ("o");
	  else
	    printf ("-");
	}
      printf ("\n");
    }
  // line 6 same like line 4
  // line 7 same like line 3
  // line 8 same like line 2
  // line 9 same like line 1
