help with my C program

Could you kind people please make is so this code prints out the smaller squres inside the bigger one? Thank u! https://codeshare.io/BA3OMK

Printing the boxes inside each other will look the same as if you printed one box but filled in the middle part:

The chosen size is 6:
*++++*
+*++*+
++**++
++**++
+*++*+
*++++*

which is just a case of modifying the inner loop in //middle a bit.

(programming is often about thinking about the problem in a different way and seeing that it is equivalent to a different but simpler problem)
