使用C++标准库时编译错误。。。

错误信息如下:

和非标准库混在一起了，怎么区分呢？用的是AIX xlC

[chenhu_doc]

命名空间出了问题吧！

[OOPhaisky]

楼主是不是同时使用了<iostream>和<iostream.h>了？

[believefym]

ambiguous

[liken218]

应该是引用的文件里有用的。而在头文件中用了using namespace std;

[fangrk]

最好给出点源代码

[wei_feihong]

#include<iostrem>

using namespace std;

[jixingzhong]

不要使用 .h 方式包含，
用 C++ 包含方式：

#include<iostrem>

using namespace std;

[chenhu_doc]

支持命名空间的引进

建议用：
#include<iostrem>

using namespace std;

代替.h的出现！
