bash's syntax is different from the C-like languages, and bash's handling of
complicated data structures leaves something to be desired.  But it's an OK
place to start to learn about programming concepts.

I think you'd get confused by trying to learn two languages at once.

I'm guessing you forgot to #include<stdlib.h> .  This is one of many errors
that beginning C programmers always run into.  I know I ran into the same
thing years ago.  "man 3 exit" will tell you which include file exit() is
defined in.  "man 3 $FUNCTION" can provide a bunch of useful info about the C
library function $FUNCTION , and many things not in the base C library also
have man pages in section 3 which are really useful if you've forgotten any of
the details.
