RH 9.0 C++编译出问题,帮忙!!

Sun1981

最近刚装了RH 9.0,以前都没有用过

今天试试C++编译却出错了

文件名:ctest.cpp

#include <iostream.h>;
                                                                                
int main()
{
        cout<<"yes"<<endl;
        return 0;
}

这到底是怎么回事啊?

#include <iostream>;
using namespace std;

不要用#include <iostream.h>;编译就OK了
