Overloading Operators & Polynomials - C++

[Kourosh23]

Imagine you are given this polynomial x + 2x^2 and you want to subtract it by 2. How can you do this using the operator minus overloading ?

My guess would be:

  Polynomial Polynomial::operator-(Polynomial object1, double constant){
     object1[0]-= constant;
     return object1;
}

Note: I am using the class Polynomial. And the program is a header file .h , not .cpp.
