As a C beginner, you'll find that C is annoyingly picky about curly
braces and semcolons.

All programming languages are picky about syntax.

Indeed. It looks different, and it _is_ different. Seems like a good
thing to me. I like programs to do what it looks like they are going
to do.

In C, this doesn't do what it looks like it's supposed to do.

   if (foo)
     do_this();
     and_this();
   then_do_this();
