You misunderstand what the IOCCC is about. It's a game. Nobody trying to write useful code will do anything like what IOCCC writes.

I doubt you will find anyone at all on this list who criticizes legible code.

I did. I made two suggestions:

1) Don't use bare semicolons in while/for constructs.

Use the continue statement instead.

2) when comparing to a literal (or a constant expression), put the literal on the left hand side of the boolean:

  if (value = literal)
    stuff;


when it is intended

  if (value == literal)
    stuff;


You can make this mistake, the compiler won't alert you, and you may spend hours trying to figure out what is wrong.

Instead do it like this:

  if (literal == value)
    stuff;


and not

if (literal = value)
    stuff;


which the compiler will flag as an error.

The compiler is your friend, if you help it a bit.
