Question

In C++:

Implement a class Polynomial that uses a dynamic array of doubles to store the
coefficients for a polynomial. This class does not need the method the
overloaded += operator. Your class should have the following methods:

Write one constructor that takes an integer n for the degree of a term and a
double coefficient c for the coefficient of the term and creates the polynomial c x^n.
(This constructor can be given default arguments easily to have a default constructor.)
Remove the existing constructor.

Write one constructor that takes an array of doubles and the number of entries
and uses the array to make a Polynomial object. Use the append method to do this.

Overload the operators +, -, and * so you can add, subtract and multiply
polynomials.

Overload the output operator << so you can output a representation of your
operator to cout or a file.

Overload the [ ] operator so you can extract or change a coefficient of a
polynomial.

Write a method degree that returns the degree of the polynomial.

Write a method eval that takes a double argument x and returns the value of the
Polynomial at x.

Be sure to write a destructor, copy constructor, and assignment operator

--

The Polynomial class should have private member variables coeffs_ for the array of
coefficients, size_ for the number of positions used in the array, capacity_ for the
capacity of the array of coefficients.

Output: Polynomial and Polynomial.cpp
