please help in project c++ 2010

[newprog135]

my project is
Develop class Polynomial.This internal representation of a polynomial is an array of terms.Each term contains a coefficient and an exponent, hence you can have an array for coefficients and exponents as a member of your class(maximum number of terms will 100 however your class should also contain a member variable that indicates how many terms are there in a given instance of the polynomial class).
the term 2x^4 has a coefficient of 2 and 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
i have tried but i failed
so please help me in building the code
please help me in building this code

  #include<iostream>

	int getE(){return Exponents};
	void getUserInput();
	friend Polynomial operator+(const Polynomial&);
};

Polynomial operator+(Polynomial&A,Polynomial&B){ //Adds two polynomial objects when exponents become equal in the loop
Polynomial C;
for(int i=0;i<100;i++){
if(A.getE()[i]==B.getE()[i]){
C.getE()[i]=A.getE()[i];
C.getC()[i]=B.getE()[i]+A.getE()[i];
