公共标题 [英] public headers

问题描述

您好，

i想要创建c ++库（供我使用），但我不知道我怎么做b $ b必须做的只有公共标题只包含公众声明。

我在C中用来将* .c中的私有声明和* .h中的公共

声明放在一起。但是如何在c ++中做到这一点。

如果有人可以帮助我，他会很好。

谢谢。

你认为C / C ++在

方面有什么区别？将您的公共声明放在.h文件中，将您的私有

声明和定义放在.cpp中。现在，不要让公共和私人访问说明符的存在让你感到困惑。这些不是你以前在C中所拥有的（据我所知），这些是为了防止错误，而不是真正保护你的知识产权。

很多。

将您的公开声明放在.h文件中，放入您的私人
.cpp中的
声明和定义。

是的，但我的意思是我有一个私人和公共成员的课程，而且我只需要公开显示在标题中而不是私有。

我知道，我只是认为如果会员是私人的，那么标题中一定不能是

这是不正确的。它必须在标题中，否则编译器将无法正确创建对象，因为它必须创建（new）

任何具有该对象的实例私人物品的空间正确

点。


如果你真的想要隐藏这些细节，你需要实现一个

抽象基类，或类似的东西。

Hello,
i want to create c++ libraries (for my use) but I don''t know how I
must do to have headers which contain only the public declarations.
I used in C to put the private declarations in *.c and the public
declaration in *.h. But how to do that in c++.
If someone could help me, he would be nice.
Thank you.

What difference do you think exists between C and C++ in that
respect? Put your public declarations in .h files, put your private
declarations and definitions in .cpp. Now, don''t let the presence
of ''public'' and ''private'' access specifiers confuse you. Those are
not what you used to have in C (as I understand it), those are to
prevent errors, not really to protect your intellectual property.

Many.

Put your public declarations in .h files, put your private
declarations and definitions in .cpp.

Yeah but I mean I got a class with private and public members and I
just want the public appear in headers not private.

Now, don''t let the presence
of ''public'' and ''private'' access specifiers confuse you. Those are
not what you used to have in C (as I understand it), those are to
prevent errors, not really to protect your intellectual property.

I know it, I just think that if a member is private it must not be
present in headers.

That''s incorrect. It must be in the header or the compiler will not
be able to create the object correctly, since it has to create ("new")
any instances with the space for the private items in the correct
spots.

If you really want to hide those details, you need to implement an
abstract base class, or something along those lines.
