使用静电？ [英] Use of static ?
问题描述
你好：
我试图理解在这个程序中使用静态。
http://nanocrew.net/sw/nscdec.c forreverse矩阵。
如果它不是静态的那么会有什么不同，只是const
unsigned char inverse [128]"在它已经是全球空间？
谢谢。

在这个例子中它不在全球空间：使用静态场所
it在文件范围内。如果它是全局的，那么其他例程可能会查看数据或者可能修改数据（const不会 - 估计 -
只读，它只是 - 提示 - 只读。）

编程就是在你忙于制定其他计划的时候发生的事情。

有意义。我不是在盒子外面思考（在他的代码之外，因为这不是b $ b不是项目的一部分）。谢谢。
（const不是-promise->只读，它只是-hints-只读。）
只有当编译器没有抱怨l值错误。

Hello:
I am trying to understand the use of static in this program.
http://nanocrew.net/sw/nscdec.c for "inverse" matrix.
What difference would it make if it were not static and just "const
unsigned char inverse[ 128 ]" in global space which it already is ?
Thanks.

It isn''t in global space in that example: the use of static places
it in file scope. If it were global then other routines could peek
at the data or possibly modify the data (const doesn''t -promise-
read-only, it only -hints- read-only.)

Makes sense. I wasn''t thinking outside the box(outside his code as this
was not part of project). Thanks.
(const doesn''t -promise-> read-only, it only -hints- read-only.)
Only if the compilers didn''t complain about l-value error.
