全球，静态，本地，寄存器变量，空闲存储器和程序指令是否存储？

Where does global, static, local, register variables, free memory and C
Program instructions get stored?

在很大程度上取决于你的编译器/操作系统。


本地人通常存储在堆栈或寄存器中，全局初始化数据包含在某些.data段中的未初始化数据，。bss段中的未初始化数据。但那只是grosso modo，而不是bros modo。回答，因为没有一般有效的。


您的编译器可能会将它存储在不同的段中，但这个想法将与

完全相同。

Depends largely on your compiler/OS.

Locals are usually stored on stack or registers, global initialized data in
some ''.data'' segment, uninitialized data in the ''.bss'' segment. But that''s a
mere "grosso modo" answer, since there is no generally valid one.

Your compiler may store it in different segments, but the idea will be
pretty much the same.

无关紧要，只要这些实体的行为符合

标准中的规定。据你所知，精灵们可以在一些小块的纸上划开笔记并将它们传递给其他精灵阅读。

It doesn''t matter, so long as those entities behave as specified in
the standard. Elves can scratch notes on little bitty pieces of
paper and pass them to other elves for reading, as far as you know.

那就是编译器/操作环境的恶化。 C没有

要求你需要知道。

That''s at the disgression of the compiler / operating environment. C doesn''t
require you to need to know that.
