For /while loop confirmation
posted 14 years ago
Don't try to think about which loop is faster, for, while, or do-while. Try to think about which loop is most appropriate for a particular situation. When you know exactly how many iterations you must go through, use the for loop. If the loop has an unknown amount of iterations, and may possibly not be executed at all, use the while loop, it's a zero or more iteration loop. When you know you need to execute a piece of code first, then check for a certain condition and possibly execute that piece of code again, use the do-while loop, it's a one or more iteration loop. I honestly don't know which loop would be "faster", but I bet if you use the method I described above to determine which loop to use, you'll always pick the "correct" loop, and probably the fastest.
