Qt’s QList class provides several methods for getting the number of items in the list – count, length, and size. As we all know, consistency is important, so which should be the canonical/preferred method to use of those 3?

I agree with everything @Cogwheel said, but in all honesty I would just pick one and stick with it. I think good style would dictate that if “size” sounds the best to you, then use “size” everywhere…don’t alternate between “count”, “length” and “size” haphazardly. That will lead to potential confusion or a lot of unnecessary trips to documentation pages.
You could try to come up with some other kind of rationale, but the language itself isn’t even consistent. All the STL containers (e.g.
list,vector) only provide “size”, thestringclass provides “size” and “length”, etc.Pick your favorite (or if you have multiple developers, you should all agree on a favorite) and just stick with it.
