编号C代码甚至不需要*编译到特定机器的机器上

代码。通常它不是 - 它被编译（翻译）成特定的

机器的汇编语言。它甚至可以编译成一些完全不同的语言。或者它可能根本没有编译（C

口译员存在）。


无论如何，这样的标准是不切实际的。那里有太多的b / b $ b种机器和太多种机器代码，对于这样一个实用的b $ b标准。

No. C code need not even *be* compiled into a particular machine''s machine
code. Often it is not - it is compiled (translated) into a particular
machine''s assembly language instead. It could even be compiled into some
completely different language. Or it might not be compiled at all (C
interpreters exist).

In any case, such a standard would be impractical. There are just too many
kinds of machine out there, and too many kinds of machine code, for such a
standard to be practical.

是的。大多数处理器供应商将为优化编译器的编写者提供大量文档和

建议和指南。例如，

英特尔在网上免费提供所有这些：
http://www.intel.com/products/processor/manuals/

Yes. Most processor vendors will provide extensive documentation with
advice and guidelines for writers of optimizing compilers. For example,
Intel provides all this for free on the web:

是的，我同意，C也许是编译语言。但是当人们说b代码比任何语言都快时，但如果我们使用不同的编译器我就不会这样做（因为你说没有编译的标准） />
代码）

yes i agree , and C is perhaps a Compiled language. But when people
say C code is faster than any language but i will not be true if we
use diffrent compilers(as u said there is not standard of compiled
code)
