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: 
2x4
has 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:
o Overload the addition operator (+) to add two Polynomials. 
o Overload the subtraction operator (-) to subtract two Polynomials.
