使用ms visual c ++ 6.0的iostream.h？ [英] iostream.h with ms visual c++ 6.0?
问题描述
你好，
我想用一个教程来迈出第一步。我使用MS Visual c ++ 6.0和
Win 98.当我尝试编译hello world时程序使用< iostream.h>
库和cout<< hello world，编译器告诉我cout。是一个
未声明的标识符。但它没有告诉我包括iostream.h
导致任何问题。我在德国新闻组中读到，而不是
< iostrem.h>，只需< iostrem>必须包含在MS Visual C ++和
下，必须使用std :: cout。但是当我尝试这个时，编译器说
引用#include< iostream>：eh.h仅适用于C ++。我该怎么办？
提前非常感谢，
莫里茨
Hello,
I want to use a tutorial to take first steps. I use MS Visual c++ 6.0 and
Win 98. When I try to compile a "hello world" program using the <iostream.h>
library and cout << "hello world", the compiler tells me that "cout" is an
undeclared identifier. But it does not tell me that including iostream.h
causes any problems. I read in a german newsgroup that instead of
<iostrem.h>, simply <iostrem> has to be included under MS Visual C++ and
that std::cout must be used. But when I try this, the compiler says
referring to #include <iostream>: "eh.h is only for C++". What should I do?
thank you very much in advance,
Moritz

怎么做？
如果您的源代码文件以.c结尾，则其编译为C。代码而不是
以你喜欢的方式工作。
#include< iostream>是适当的C ++形式。还记得cout在
命名空间std中。所以你需要std :: cout。

do?
If your source code file ends with .c it is compled as "C" code and not
"C++", use .cpp as the file extension to compile as "C++". Or configure VC
to work the way you prefere.
#include <iostream> is the proper C++ form. Also remember cout is in
namespace std. So you will need to std::cout.

确保你'' re filename被称为something.cpp。听起来好像你是调用C编译器而不是C ++编译器。
关于< iostream>的建议或者< iostream.h>适用于所有编译器。只有
< iostream>是正确的C ++。
john
Make sure you''re filename is called something.cpp. It sounds like you are
invoking the C compiler not the C++ compiler.
The advice about <iostream> or <iostream.h> is true of all compilers. Only
<iostream> is correct C++.

请按照新闻组中的建议进行操作。
另外，你可能想要一本好书来学习C ++。
" Accelerated C ++"非常适合初学者。
必须使用std :: cout。但是当我尝试这个时，编译器说

iostream.h is an old header that should not be used anymore.
Please do as suggested in that newsgroup.
Also, you might want to get a good book to learn C++.
"Accelerated C++" is very recommended for starters.

你的问题在这里是offtopic，因为你有问题
使用特定的编译器，而不是语言本身。
请在相应的
NG中询问编译器特定的问题，例如microsoft.public.de.vc（一个致力于VC ++的德语）
尽管如此，你的问题出现了，因为你已经命名了你的
源文件.c编译器认为你想要C语言中的程序。
所以只需将源文件重命名为.cpp就可以了。

Your question is offtopic here, because you have problems
with a particular compiler, not the language itself.
Please ask compilerspecific questions in the appropriate
NGs, e.g. microsoft.public.de.vc (A german ng dedicated to VC++)
Nonetheless, your problem arises because you have named your
sourcefile .c the compiler thinks you want to program in C.
So simply rename your sourcefile to .cpp and it should work.
