The display looks something like this:
0
0 0
0 0 0
0 0 0 0
0 0 0 0 0
0 0 0 0 0 0
I want the display to look like this:
           0
          0 0
         0 0 0
        0 0 0 0
       0 0 0 0 0
      0 0 0 0 0 0

Please edit your post to use code tags - http://www.cplusplus.com/articles/jEywvCM9/


#include "Chapter 9.h"; Classes/files with space in the names, is not a thing.

Edit: Also please show us what output you are getting, and what output you are expecting.
