I am VERY new to C++ and Open GL and I have been trying to display 3D objects in a scene. it worked fine with one but when I tried to alter my code to add a second, my code regarding the HUD text showing the camera location started giving errors. The error above is shown and it is apparently in the sstream file (#include). I have tried searching around and asking for help but there is nothing that helps/that I understand. When I comment-out the #include line and the code that uses it, I get a similar saying "error C2143: syntax error : missing ';' before 'using'" in my main.cpp file.
I am running Visual Studio 2010 and I have even tried turning the whole thing off and on again, and copying the code over to a new project. Help would be greatly appreciated.

I haven't changed the code and as far as I am aware, there are semi-colons where there are meant to be. Even my friend who has been programming for 5 years couldn't solve this. I will include any other specific code if needed. And when I said new to C++ and OpenGL I really much VERY new. This is even my first post. I'll get there eventually.
you have to put a ';' after each class
That means
class foo{
public:
void bar();
};
and i think you miss the last semicolon.
