I have the following problem: This error appeared to me, when I compiled the source code:

`error C4430: missing type specifier - int assumed`

This error occurs when a variable is not initialized with any type (like a integer, float or any custom type of object). But, I have a type initialized and it's not recognizable, although I have more classes, which are similarly built like the trouble one, and they're running fine.

So, my problematic class is the following one:

```
class Rectangle
{
    float x1, y1, x2, y2;
    bool created;

public:
    Rectangle() { created = false;}
    Rectangle(float x1, float y1, float x2, float y2);
    ~Rectangle() {}
    bool isCreated() { return created;}
    void setCreated( bool c) { created = c;}
    float getX1() { return x1;}
    float getX2() { return x2;}
    float getY1() { return y1;}
    float getY2() { return y2;}
};

```

An example of a working class:

```
class Triangle
{
private:
    vector<float> x, y, z;
    bool created;

public:
    Triangle() { created = false;}
    Triangle(vector<float> x, vector<float> y, vector<float> z);
    ~Triangle() {}
    bool isCreated() { return created;}
    void setCreated( bool c) { created = c;}
    vector<float> getX() { return x;}
    vector<float> getY() { return y;}
    vector<float> getZ() { return z;}
};

```

Finally, the code fragment where the errors occur:

```
class Primitive
{
private:
    string index;
    Material mat;
    Texture text;
    int count;
    Rectangle rect; //error detected in this line
    Triangle tri;
    Cylinder cyl;
    Sphere sph;
    Torus tor;

public:
    Primitive() {count = 0;}
    Primitive(string id, Material mt, Texture tx);
    ~Primitive(void);
    string getIndex() { return index;}
    Material getMaterial() { return mat;}
    Texture getTexture() { return text;}
    void addRectangle(float x1, float y1, float x2, float y2);     //error detected in this line
    Rectangle getRectangle() { if(rect.isCreated()) return rect; else return Rectangle(); }   //error detected in this line
    void addTriangle(float x1, float x2, float x3, float y1, float y2, float y3, float z1, float z2, float z3);
    Triangle getTriangle() { if(tri.isCreated()) return tri; else return Triangle(); }
    void addCylinder(float bs, float tp, float hei, int sli, int stac);
    Cylinder getCylinder() { if(cyl.isCreated()) return cyl; else return Cylinder(); }
    void addSphere(float rad, int sli, int stac);
    Sphere getSphere() { if(sph.isCreated()) return sph; else return Sphere(); }
    void addTorus(float in, float out, int sli, int loo);
    Torus getTorus() { if(tor.isCreated()) return tor; else return Torus(); }
};

```

Any ideas about how to correct it?

EDIT: My includes are:

```
#include "Material.h" //custom class
#include "Texture.h"  //custom class
#include <iostream>

```

The compiler is `Visual C++ 2010`.
