Thread: for loop question

Lesson number one, read this . I've added them to your post this time round...

Now to your question:
>>how do I get the first asterisk to be in the middle
Either put the spaces out yourself, or use the %10s type method.

This has been done many times before, I'm sure a board search will find you an example.

Hi everybody,

I stumbled upon this site while looking for some help to a problem I have and this seems to be a great community. My question has to do with a for loop and the printing of a triangle. What I need to do is print a triangle like this:

Triangle

Code:

          *
        ***
      *****
    *******
  *********
***********

However, I am getting something like this:

Triangle

Code:

*
**
***
****
*****
******
*******
********
*********
**********
***********

My code so far is:

Code:

#include <stdio.h>

main()
{
  int width=0, row=0, column=0;

  scanf("%d", &width);

  for(row=1; row<=width; row++)
    {
      for(column=1; column<=row; column++)
        printf("*");
      printf("\n");
    }

  return 0;
}

So my question is how do I get the first asterisk to be in the middle of the triangle like this first example I gave. I would appreciate any help you can give me since I am very new to computer programming. Thanks!

how about tryin to use gotoxy() functions.....
that would help....

Actually, I think the output is supposed to look like this:

Code:

     *
    ***
   *****
  *******
 *********
***********

Oh. It looks like its centred in the reply box. Stupid non-fixed width fonts.

I was really trying to get a triangle output like the one Xsquared did. I am trying to get the first asterisk in the middle of the rest of the triangle. Can anybody help?
