Should we still be optimizing “in the small”?

Question

I was changing my for loop to increment using ++i instead of i++ and got to thinking, is this really necessary anymore? Surely today\'s compilers

Answer 1

I wanted to add a little something. This "premature optimization is bad" is kind of rubbish. What do you do when you select a algorithm? You probably take the one with the best time complexity - OMG premature optimization. Yet everyone seems fine with this. So it seems like the real attitude is "premature optimization is bad - unless you do it my way" At the end of the day do whatever you need to do to make the app you need to make.

"The programmer shall left shift by one instead of multiplying by 2". hope you dont want to multiply floats or negative numbers then ;)
