What do you prefer:

for(int i = 0; i <= maxValue; i++)

Or

for(int i = 0; i < maxValue + 1; i++)

=

Definitely:

for (int i = 0; i < maxValue; ++i)

<=

maxValue = maxValue +1
for(int i = 0; i < maxValue; i++)

I prefer not writing for loops unless I really need to. If I need to, I'll use foreach or for ... in syntax, depending on the language.

I make an effort to not write the classic for-loop.

Use map, filter, reduce or any more abstract sequence helper function. It's far more readable and really describes your problem.

Removing side effects is a nice bonus.

@Agred where is +1??

@sudo-rm-rf About going places, what do you mean with that ?

@FilipeRamalho Well, I cannot use the same variable again later on code. (I guess places means elsewhere in the code)

@k0pernikus If this was js, I would consider. It is my fault for not specifying the language, though. C#

@Agred I didn't see that one comming. But this way, I never really use index 0.

@Mitiko There are ways to achieve that if you only want it hard enough ;) (or use a library): https://stackoverflow.com/q/40075/...
