1在'for'循环递增落后时格式化技术的原因？ [英] Technical reasons behind formatting when incrementing by 1 in a 'for' loop?

问题描述

所有网站上，code样品具有为循环看起来是这样的：

All over the web, code samples have for loops which look like this:

for(int i = 0; i < 5; i++)

而我用的格式如下：

while I used the following format:

for(int i = 0; i != 5; ++i)

我这样做，是因为我相信它是更有效，但是这究竟是在大多数情况下，有关系吗？

I do this because I believe it to be more efficient, but does this really matter in most cases?

DenverCoder8's bench marking clearly deserves some recognition as well as the compiled versions of the loops by Lucas. Tim Gee has shown the differences between pre & post increment while User377178 has highlighted some of the pros and cons of < and !=. Tenacious Techhunter has written about loop optimizations in general and is worth a mention.
