POLL: Programming style - i++ vs. ++i
-
In terms of compiler optimization intelligence, I think we've finally surpassed the smarts of the VAX FORTRAN compiler of the late 80's. A human being could not write code that was more efficient than what that compiler generated.

I rarely use ++i because then I would have to take a few seconds to think on which order things are executed... John

I wish there was a neither option. I try to avoid both and use i += 1. Two reasons : I wrote a scripting engine and I saw little reason for the ++ and -- operators and did not include them. This got me into the habit of using the += and -= operators which I did include. Second reason - if, for some odd reason, the incrementer needs to change to a 2 it is easier. Actually, a macro or "const int" value for the incrementer is a better way to go which I prefer to use along with the += and -= operators. Bottom line - I prefer the += method to be as consistent as possible but that's just me. __________________________________________ a two cent stamp short of going postal.

After a batch of interviews, the second most notable thing is that where both
++iandi++are possible, all candidates usedi++Having optimizied for older compilers I automatically opt for the "simpler" concept of ++i except where I explicitely need the postfix increment. (I now that it makes no difference to today's compilers, but it might still save some microseconds when compiling :rolleyes: ) so - Vote 5 if it'sfor(int i=0; i<n; ++i), and Vote 1 if it'sfor(int i=0; i<n; i++)for you. if the "programming" in the title triggers a pawlowian in you, please vote 3

++i, for sure. Although a compiler may optimise, it's in theory more efficient, and never less so. Christian I have drunk the cool-aid and found it wan and bitter. - Chris Maunder

sighist || Agile Programming | doxygenStrange for incrementing integers in for statements I use i++ For incrementing itterators I use ++it. Ant. I'm hard, yet soft.
I'm coloured, yet clear.

exactly my thought - dunno why you were voted down...
