Polynomial
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 (*=).
