Need help with "shooting a projectile" and a "password menu"

That wasnt the point. The point was that you're missing the subtlety of programming, where small differences, although they appear to be similar, are't exactly the same.

Can be confused with trolling.

Turing:

var list : array 1 .. 10 of int := init(1,2,3,4,5,6,7,8,9,10) list(Rand.Int(1,10)) := list(Rand.Int(1,10)) + 1 % vs list(Rand.Int(1,10)) += 1

Is very interesting, but is that really a subtly in the increment operand, or common sense?

+= would definitely be superior in this situation, in my opinion. But as writing code myself, if I saw this problem, I would simply store (Rand.Int (1,10)) into a temp variable.

In a lot of cases it wont make a difference, anyways.

its simply quicker to type

[mirhagk]

and as Tony pointed out, technically could be slightly faster (although probably not if there is a good compiler *cough* not turing *cough*)
