I’ve seen code that look like this:
int delay = 15 * 60; // 10 minutesEven if the comment was on the same line someone forgot to update it. People just ignore comments.
Better solution is to write (in C#):
TimeSpan delay = TimeSpan.FromMinutes(15)Much more obvious what the code actually means.
Is the better way is a runtime performance hit. Does the compiler optimize this?
It’s probably a little bit slower, but there are other things more worth to optimize than to shave off a few microseconds from a 15 minute delay.
Yeah, it adds up eventually when working with embedded platforms, but for PC stuff I agree.
If you’re working in embedded I guess you can probably make an inline function or a macro so it’s taken care of at compile time.
