Error C2143: syntax error : missing ';' before 'namespace'

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.

#include <Windows.h>
#include <GL/gl.h>
#include <GL/glu.h>
#include "glut.h"
#include "SceneObject.h"
#include <fstream>
#include <sstream>
#include <iostream>
#include <string>
//#include <cmath>
//#include <limits>
//#include <cstdlib>

using namespace std;

...

stringstream ss;
ss << "Camera (" << cam.pos.x << ", " << cam.pos.y << ", " << cam.pos.z << ")";
glClear(GL_DEPTH_BUFFER_BIT);
outputText(-1.0, 0.5, ss.str());

            colours[i].g = ((float) rand() / (RAND_MAX+1));
            colours[i].b = ((float) rand() / (RAND_MAX+1));
        }
    }
    else if (randomCol == 'n')
    {*/
        for (int i=0; i < NUM_COL; i++)
        {   
            inFile >> colours[i].r;
            inFile >> colours[i].g;
            inFile >> colours[i].b;

    inFile >> NUM_TRI;
    indices = new tri[NUM_TRI];

    for (int i=0; i < NUM_TRI; i++)
    {   
        inFile >> indices[i].a;
        inFile >> indices[i].b;
        inFile >> indices[i].c;
    }

    inFile.close();
    return 0;
}
}
#endif

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.
