ç编译成机器code和不要求语言本身的运行时支持。这意味着它可以写code，可以之类的东西的文件系统，虚拟内存，进程和别的但是寄存器和RAM存在之前运行。

C compiles down to machine code and doesn't require any runtime support for the language itself. This means that it's possible to write code that can run before things like filesystems, virtual memory, processes, and anything else but registers and RAM exist.
