Hi !
If you can solve this problem, you are a really
expierienced programmer !!

look:

template<class T> class VEKTOR3D
{
 protected:
 public:
  T x,y,z;
  // ok thats a standard way. but if you want to assign
  // VEKTOR3D<int> a with VEKTOR3D<float> b, the compiler
  // says, that it cannot convert the types.

  VEKTOR3D<T>& operator=(VEKTOR3D<T>&t){ x=t.x;y=t.y;z=t.z;return *this; }

  // so I tried the following:
  template<class TT> VEKTOR3D<T>& operator=(VEKTOR3D<TT>&t) { ....
  // and he gives me an syntax error !!!!!
  // even this dont work:
  template<T,class TT> VEKTOR3D<T>& operator= .....
};


// and this  is also not possible, because the compiler wants operator=
// to be a member function
template <class T,class TT> VEKTOR3D<T>&operator=(VEKTOR3D<T>&t,VEKTOR3D<TT>&tt) { ....

So, does the ANSI-Comitee missed something or is there another way to
solve this problem ??????


So, where are you, big C++ Wizards ??
