为什么选择for（;;）{} over while（1）？ [英] Why choosing for (;;){} over while(1)?

问题描述

可能重复：

for（;;）的速度比while（TRUE）快吗？

我看到这个

for (;;)
{
  // Some code here
} 

但是，它提供了什么好处，为什么不选择 while（1）{} ？

quite often. But what benefits does it offer and why just not choose while(1){}?

推荐答案

它们产生相同的代码。有几个原因为什么你可能更喜欢<; c $ c> for（;;），但它只是个人偏好：

They produce identical code. There are a couple of reasons why you might prefer for (;;) but it is all just personal preference:

1. 一些编译器会警告你总是正确的条件。 for（;;）不会有这个问题。

for ;;）逐字地读为Just loop forever！，而 while（true）仍然

for (;;) literally reads as "Just loop forever!", whereas while (true) still appears to have some kind of condition.

我说的选择一个，坚持下去。没关系，只要你不任意在他们之间切换。

I say pick one and stick with it. It doesn't matter as long as you don't switch between them arbitrarily.
