Polynomial class?

Hello everybody,

I hope somebody here can help me out. I got a program to do for class but for some reasion I just can't put it togther. For those of you with C++ How to Program book third edition by Deitel & Deitel its Ex 8.19 p575...

Those without the book here is the question:

Develop class Polynomial. This internal representation of a Polynomial is an array of terms. Each term contains a coefficient and an exponent. The term
2x^4
has a coefficient of 2 and an exponent of 4. Develop a full class containing proper constructor and destructor functions as well as set and get functions. The class should also provide the following overloaded operator capabilities:
1. Overload the addition operator (+) to add two Polynomials.
2. Overload the subtraction operator (-) to subtract two Polynomials.
3. Overload the assignment operator to assign one Polynomial to another.
4. Overload the multiplication operator (*) to multiply two Polynomials.
5. Overload the addition assignment operator (+=), the subtraction assignment operator (-=), and the multiplication assignment operator (*=).

well people I just can't put my head into this. any help is apresiated... hints examples anything... and if your free I really need it during these next couple of days...

Thanks in advance for any help......
