right there. Don't assume the compiler fixes everything. Compile time is the absolute worst time to try to figure out what a programmer "wants" to achieve and then attempt to get there. Some compilers do a better job than others, so it depends on which compiler you are using. Is that a Fuji apple or a Granny Smith? Smile | :)

I am not saying every programmer has to learn what the compiler does with their code. But if you are actually concerned with, or absolutely need performance, then you MUST know what the compiler will do with your code. Hand tuning an algorithm might take half an hour and save you 75% of your execution time. A large error could save you considerably more. A compiler can only do so much with junk code before it also outputs junk.

Compilers aren't mind readers and none that I know of have heuristic analysis to try to figure out what your intent was. Until they make a mind reading compiler, we're all in the same boat. A compiler actually listens to what we tell it, even when we want it to obey what we mean, not what we type.
