c programming source code sharing #6 : Printing a hollow square using nested for

ASSALAMMUALAIKUM W.B.T. peeps !

hi hi hi. (greeting ni, "hai hai hai" bukan gelak hi hi hi)
so today i would like to share the next source code, of my homework this week, freshly from oven!
*baru siap buat daa*

sample question:
Read an integer(entered by user) and prints a hollow square. the number of '=' used to draw line of each sides of square.

example, user enter 5, so the output is

=====

=      =

=      =

=      =

=====

a 5x5 square with a hollow.(hollow-lubang)

(not-so-square looking here, but in .exe file you'll see it is more like a square!)

another sample output:

of course, it will only works with positive integers.

& for integer=1 & 2, you'll not see a hollow.

soooo here's the screenshot of my source code:

or, download the c-file here. (can edit&try compile yourself!)

my lecturer told us, usually for this kind of question, there would be more than 1 solution. so my fellas out there, if you have a simpler & more unique way, please share! sharing is caring yow! & for any questions, please, just ask me ok? :)
