An oft-quoted C idiom (the cuteness of which does wear off a bit) was exhibited - apart
from in Unix sources - in the K&R book. To understand it one might have to realise
that adding a constant to a pointer, and dereferencing, is equivalent to p[constant]:
mystery(char *s, char *t) {
while(*s++ = *t++)
;
}
The *(p+c) business cannot remain mysterious if one wants to write idiomatic C. I would
tend to prefer the idiom above to a tedious loop with counter and []'s written
longhand, though a comment might be warranted.

And I would tend to prefer a loop that involves some sort of bounds checking :).
