C program that prints out this pattern : [on hold]

I need a c program that gets a number from the user and prints out this pattern. For example the user enters the number 4 :

    0
   010
  01210
 0123210
012343210
 0123210
  01210
   010
    0

Thanks! Unfortunately I'm not really familiar with StackOverFlow's text editor! So here is a picture : enter image description here
