Need the C++ code of this excercise

You will implement and test a polynomial class, using fixed-sized array as the data structure to store the terms in a polynomial. Each term in the polynomial is also a class that you will need to implement. Recall that the general form of a polynomial is as follows: P(x) = anx" + an-1x"-| + + aix + ao Here, each term has a coefficient, denoted as a, and a exponent i, which represent the power of the variable x. Your polynomial class must implement the following operations: Addition-given two polynomials P and P , compute the polynomial F-P + Subtraction-given two polynomials P and R, compute the polynomial -R- 3. Multiplication - given two polynomials P and P, compute the polynomial P,-P*P 5. Indefinite integral -given a polynomial P, finds its indefinite integral (anti-derivative). 1. 2 4. Derivative- given a polynomial P, finds its derivative. 6. Definite integral given a polynomial P, evaluate its definite integral over an interval [a,b] 7. 8. Degree-given a polynomial P, find its degree (the largest exponent in any term). Evaluate- given a polynomial P, evaluate it at value x, to compute y- P(r) You must first implement the polyterm class, which implements a term in a polynomial. You will use a fixed-size array to store the terms in the polynomial, in decreasing order of exponent. Thus, each element in the array represents a term in the polynomial. The array will have a maximum size CAPACITY that limits the number of terms that can be added to the polynomial
