hi in my text book i have this problem.
how to program this

``````Define a class Quadratic_int that stores the coefficients of a quadratic polynomial in a dynamically allocated array of integers. Supply the "big three" memory management functions. Use this class to demonstrate
(a) the difference between initialization
and assignment operation
s = t;
(b) the fact that all constructed objects are automatically destroyed
(c) the fact that the copy constructor is invoked if an object is passed by value to a function
(d) the fact that the copy constructor is not invoked when a parameter is passed by reference
(e) the fact that the copy constructor is used to copy a return value to the caller.
Supply a member function which calculates the value of a quadratic function for a given argument value. Overload + and - operators for addition and subtraction of two polynomials and the unary operator * which return true or false when the corresponding quadratic equation has or has not real roots. Overload the stream operators << and >>. Demonstrate all these functions and operators.``````

thnx for help

Now, Where's your code? Haven't you tried solving this problem yourself? Post your progress if you've attempted this.. Else, have a go @ it, then come back if u have any problems....

When is the assignment due, that is, how much time do you have before you have to turn it in? Have you studied c++ classes and arrays yet?

Since you are reading the book, I assume you have some knowledge, so here is a basic start

``````class Quadratic_int{
private:
int *coefficients;
public:
