Thread: calling the class within the public...help!

I think this is a pretty simple problem, but I just can't get it, I have the following class:

Code:

class Polynomial
  {
  private:
   int coeff[LEN];

  public:
   Polynomial ();
   Polynomial Add (const Polynomial& P2) const;
   Polynomial Subtract (const Polynomial& P2) const;
   void Print (unsigned wid=0) const;
   unsigned width () const;
   void setCoeff (unsigned index, int newCoeff);
  };

Polynomial::Polynomial()
  {
  for (unsigned i=0; i<LEN; i++)
    {
    coeff[i]=0;
    }
  }

I'm trying to implement the Add member but I can't figure out how to access what's in P2

I've tried

Code:

Polynomial Polynomial::Add (const Polynomial& P2) const
  {
  Polynomial Ptemp;
  for (unsigned i=0; i<LEN; i++)
    {
    Ptemp = coeff[i] + P2[i];
    }
  return Ptemp;
  }

and then it gives me complier error "no match for `Polynomial &[unsigned int &]'"

So I don't know really what to do, any help would be nice
