Question #9769

Can someone help me with this

#include <iostream>

class polynomial

{

public:

// CONSTANT

static const int CAPACITY = 15;

// CONSTRUCTOR

polynomial(double c = 0.0, int degree = 0);

// MEMBER FUNCTIONS

void add_to_coef(double amount, int degree);

void assign_coef(double c, int degree);

void clear();

double coefficient(int degree) const;

void print();

int degree() const;

private:

// DATA MEMBERS

double coef[CAPACITY];

int largest_degree;

};

#include "poly.h"

#include <cmath>

using namespace std;

static const int CAPACITY = 15;

// Start implementing your functions here

#include <iostream>
