class polynomial with operator overloading

Hi ,
I'm new in C++ programming and I need help.
I wanna write a class named polynomial that can be used like this :

Code:

int main()
{
	vector<double> ac;
	ac.push_back(10);
	ac.push_back(3);
	const Poly a(ac); // a contains 3x + 10

	vector<double> bc;
	bc.push_back(1);
	bc.push_back(0);
	bc.push_back(4);
	const Poly b(bc); // b contains 4x^2 + 1

	Poly c = a + b; // c contains 4x^2 + 3x + 11
	c += b; // c contains 8x^2 + 3x + 12

	Poly d = c * 2; // d contains 16x^2 + 6x + 24
	cout << d << endl; // prints 16x^2+6x+24 in the output

	d = -1 * b; // d contains -4x^2 - 1
	cout << d << endl; // prints -4x^2-1 in the output

	cout << d(2) << endl; // evaluates d with x=2, the result is -17       // same as caling d.operator()(2)

	cout << d[0] << endl; // prints -1 which is the coefficient of x^0
	cout << d[1] << endl; // prints 0 which is the coefficient of x^1
	cout << d[2] << endl; // prints -4 which is the coefficient of x^2
	cout << d[3] << endl; // prints 0 which is the coefficient of x^3

	d[1] = 7; // d now contains -4x^2 + 7x -1
	d[4] = 1; // d now contains x^4 - 4x^2 + 7x -1
	cout << b[2] << endl; // prints 4

	return 0;
}

and I don't understand how to write inside the member functions.

//poly.h

class Poly
{
public:
	Poly( vector<double> a ):p(a){}
	
	Poly& operator+= ( const Poly& c );              //this+=c
	Poly operator* ();
	Poly operator+ ( Poly& a ) const;
	double operator()( const double b ) const;
	double operator[]( const double d ) const;

	friend Poly operator<< ( ostream& out , Poly& q );
private:
	vector<double> p ;
};

I think my class should be something like this

please help to complete my class.
thanks

 

I some how completed my class and I need help to make it the best

plz help me.

" code has been attached "

 

What do you mean by best?

 

It isn't important
It's just my slogan
I just wanna make my program run
just help me

thanks;

 

So consider that is the best method.

 

aanswer is here:-

http://ardictionary.com/Best/3450

 

I know that.

 

Great!! now u know this...

 

excuse me!
are you having fun here or really really wanting to help persons like me solve their problems :-?

 

This is one of the main reason for this

 

I don't understand!!!!!!
every one here just had answered the questions for competition and now they won't answer?????(after this )

 

That is not true from my end because I am member of this forum for quite sometime and yes some people used the competition in the wrong way and I think I had to reply back and cannot sit back see someone bashing on me.

Anyways your program is quite good.

 

ok never mind
I made my prject run myself
with my friend's help at university.
and I won't come here for solving my problems anymore.
bye
