I vote for eclipse, it likes to take up memory, but it is worth it, I do this without it:

void doSomething()
{
return someFloat;
}

Eclipse

Again, there's nothing decent anymore for website creation. I loved Quanta/Quanta+, but it's turned into some horrid beast that's absolutely useless to me or anyone else as far as I can tell.

Got to vote Emacs because it offers everything & the kitchen sink. If I were smarter, I could probably get it to do the dishes....

That said, Netbeans gets an honorable mention. Used to use Bluefish quite a bit but it doesn't seem to appeal to me much these days.

Whoa, Emacs made a much more respectable showing here than I expected - not far behind Geany and Netbeans. Rock on! :)

I've used code::blocks for a while, and I'm okay with it.
