is it legal to have constructors (even overloaded) in a struct? i tried this with no errors, but when i change something that is remotely related to this, i get weird errors. i had something to this effect...

  
struct Vertex {
  Vertex( float px, float py float pz ) {
    x = px;
    y = py;
    z = pz;
  }
  Vertex() {
    x = y = z = 0.0f;
  }
  
  float x, y, z;
  float tu, tv;
};

Not really related, but can you inherit from a struct now that they can contain member functions and data?

I''m still waiting for that FAQ. Any moderator could put an announcement with answers to stuff like this..

The only difference between a struct and a class in C++ is that a struct defaults members to public and a class defaults to private.

So yes, a struct can have constructors/destructors, virtual functions, you can inherit from them, etc., etc. Whether you use one or another is just a matter of style and personal taste.

And no, to answer the inevitable next question, there is no speed difference.
