Question

class dataReader{
private:
    ifstream gfxDataFile;
    int numVertices;
    vector<*vertexData> vertices;
public:
    dataReader();
    dataReader(string file);
    ~dataReader();
    string getLine();
    int numberOfVertices();

};

the line with the vector gives me the error

vertexData: Illegal use of this type as an expression, any help guys?

Heres the definition of vertexData

class vertexData{
private:
    float x;
    float y;
    float z;
public:
    vertexData();
    vertexData(float gx, float gy, float gz);
    ~vertexData();
    float getX();
    float getY();
    float getZ();
};

Answer 1

*vertexData should be vertexData*

Putting the * on the left means, broadly, ‘try to dereference the following expression’ – and of course what follows is not a valid expression (though even if it were you’d have other problems trying to use an expression inside a template argument list…). When declaring pointer types the * goes on the right of the type name.
