Develop class Polynomial. The internal representation of a Polynomial is an array of terms. Each term contains a coefficient and an exponent. The term 2x4 has the coefficient 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: Overload the addition operator (+) to add two Polynomials. Overload the subtraction operator (-) to subtract two Polynomials. Overload the assignment operator to assign one Polynomial to another. Overload the multiplication operator (*) to multiply two Polynomials. Overload the addition assignment operator (+=), subtraction assignment operator (-=), and multiplication assignment operator (*=).
