Let's start a war in here
@LukeAlmighty Would I be right in saying for loops can be optimised since the number of iterations can be known beforehand whereas while loops cannot?

I'm not sure about that. I believe, that you can change the iterated variable from inside the for loop.
@LukeAlmighty Disgusting. I instead vote for a third option, recursion.
@thatbrickster
I see you hate your computer's memory... 
@LukeAlmighty As an inexperienced programmer I wanted pure performance and would've been okay with mutability and reusing variables. As an experienced programmer I want correct programs that I know will perform well should they be designed properly.
@thatbrickster @LukeAlmighty Compilers often do tail calls to "unwrap" it into whats basically a for loop anyway if your function doesnt require any added stack space, and if it does, good luck
@LukeAlmighty @thatbrickster Compilers can unroll for loops with compile time values
One thing thats actually cooler though is that for loops can be parallalised with almost 0 effort while while loops can't, and these work on non-constants
#pragma omp parallel for
Before any for loop and it gets spread over as many threads as your cpu has
