bitcoin diamond:请问这段C＋＋代码那里有错误？？

#include<iostream.h>

class desk
{
public:
desk();
protected:
int weight;
int height;
int width;
int length;
};

class stool
{
public:
stool();
protected:
int weight;
int height;
int width;
int length;
};

desk::desk()
{
weight=10;
height=5;
width=5;
lenght=5;
cout<<weight<<" "<<height<<" "
<<width<<" "<<lenght<<endl;
}
stool::stool()
{
weight=6;
height=3;
width=3;
lenght=3;
cout<<weight<<" "<<height<<" "
<<width<<" "<<lenght<<endl;
}

void fn()
{
desk da;
stool sa;
}

void main()
{
fn();
}
我改完了，那里还有错误呀．．．郁闷
#include<iostream.h>

class desk
{
public:
desk();
protected:
int weight;
int height;
int width;
int length;
};

class stool
{
public:
stool();
protected:
int weight;
int height;
int width;
int length;
};

desk::desk()
{
weight=10;
height=5;
width=5;
length=5;
cout<<weight<<" "<<height<<" "
<<width<<" "<<length<<endl;
}
stool::stool()
{
weight=6;
height=3;
width=3;
length=3;
cout<<weight<<" "<<height<<" "
<<width<<" "<<length<<endl;
}

void fn()
{
desk da;
stool sa;
}

void main()
{
fn();
}

错误提示：fatal error C1010: unexpected end of file while looking for precompiled header directive
