Overloading operator=

[switcher]

I am a bit confused with overloading operator=. Here is my function call, not working of course...

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

Main.cpp

Polynomial test1; Polynomial test2; . . . test2 = test1 * test1; Polynomial.cpp -------------- Polynomial* Polynomial::operator=(Polynomial& P){ this._degree = P.getDegree(); this._coefficients = P.getCoefficients(); return this; }

1. If an operator overload is supposed to return this, it should return it as a reference, not a pointer.
2. Polynomial::operator=() should be able to access Polynomial::_degree, so there's no need to call getDegree(). The same goes for _coefficients.
3. P should be a 'const Polynomial &'.

4. this is a pointer - so this->x not this.x

We assume that you already have operator* working, too.

Damn. I knew C# was going to overwrite something. I totally ignored that dot.
