Question

This question came to mind after seeing this simple piece of code:

if (!x%y)
{
    // do something
}

Maybe it’s the influence of early C books (K&R?), but isn’t the following always preferred, if not as cute?

if (x%y != 0)
{
    // do something
}

This quote answers your question.

“Debugging is twice as hard as writing
the code in the first place.
Therefore, if you write the code as
cleverly as possible, you are, by
definition, not smart enough to debug
it.” – Brian W. Kernighan
