可能重复： “for（;;）”比“while（TRUE）”快吗？ 如果没有，为什么人们会使用它？
我想知道哪个无限循环更可取：
for(;;) { // Do some stuff }要么
#define TRUE 1 while(TRUE) { // Do some stuff }从性能的角度来看，它们之间有什么区别吗？
从编码标准的角度来看，更可取的是什么？

I would like to know which infinite loop is more preferable:
for(;;) { // Do some stuff }or
#define TRUE 1 while(TRUE) { // Do some stuff }Is there any difference between them from the performance point of view?
What is more preferable from coding standards point of view?

从性能的角度来看并不重要。 编译器将两者优化为相同的汇编代码。 从“编码标准”的角度来看，（;;）更简洁，这很好。 虽然while（TRUE）稍微清楚一点，但是（;;）是如此常见，以至于在这种情况下的清晰度并不是一个大问题（实际上，for（;;）的普遍性可能使它比while版本更清晰）。
From a performance point of view it doesn't matter. The compiler will optimize both into the same assembly code. From a "coding standards" point of view, for(;;) is more terse, which is nice. Although while(TRUE) is a bit clearer, for(;;) is so common that clarity in this case is not much of an issue (in fact, the ubiquity of for(;;) may make it more clear than the while version).
