Thread: review this code

Those are almost, but not quite, the same due to their behavior in the case of 'continue;'.

I remember reading (long ago!) about how some compilers were found to execute

Code:

for(;;) {
   /* ... */
}

faster than

Code:

while (1) {
   /* ... */
}

or variants thereof because the compiler would actually perform an evaluation of testing 1 for truth.

Basically... you just can't assume much anything about how optimization works. Just have faith that it does.
