c - PC Lint while(TRUE) 与 for(;;)

Question

我是第一次使用 PC Lint。当 PC Lint 警告我关于我的 while(TRUE) 时，我正在“检查”我的代码。

是这样写的:

716: while(1) ... -- A construct of the form while(1) ... was found.

Whereas this represents a constant in a context expecting a Boolean, it may reflect a programming policy whereby infinite loops are prefixed with this construct. Hence it is given a separate number and has been placed in the informational category. The more conventional form of infinite loop prefix is for(;;).

我没看懂这句话。谁能帮助我理解它？

Answer 1

文中说尽管 while(TRUE)(它被预处理为 while(1))是一个完全有效的无限循环，但更传统的编写形式无限循环是

for(;;)
{
   ...
} 

因为它根本不使用任何值，因此不容易出错。
