1.Develop the class Polynomial. The internal representation of a Polynomial is an array of terms. Each term contains a coefficient and an exponent. The term: 2x4has the coefficient of 2 and the exponent 4. Develop a complete class containing proper constructor and destructor functions as well as set and get functions. The class should also provide the following overloaded operator capabilities:oOverload the addition operator (+) to add two Polynomials. oOverload the subtraction operator (−) to subtract two Polynomials.
