关于#include，知道的进

蛟龙-_- 2011-04-11 08:31:33
看下面一段代码：
#include<iostream>
using namespace std;
#include<iomanip.h>
void main()
{
int a=27;
float x=3.14;
cout<<"a="<<oct<<a<<"a="<<hex<<endl;
cout<<"x="<<setw(10)<<"x="<<x<<endl;
cout<<setiosflags(ios::fixed)<<"x="<<x<<endl;
}
我是按课本上敲的，用VC6编译时竟出现102个错误，见鬼了，怎么回事
错误为：
