homework.cpp(32) : fatal error C1083: Cannot open include file:
'Polynomial.h': No such file or directory

The question is:

Using C++ language to complete this homework

1. Develop class Polynomial. The internal representation of a
Polynomial is an array of terms. Each term contains a coefficient and
an exponent. The term

2x4
has the coefficient 2 and the exponent 4. Develop a complete class
containing proper constructor functions as well as set and get
functions. The class should also provide the following overloaded
operator capabilities:

(a) Overload the addition operator (+) to add two Polynomials.
(b) Overload the multiplication operator (*) to multiply two
Polynomials.
(c) Overload the subtraction assignment operator (-) to process two
Polynomials
(d) Overlaod the assignment operator to assign one polynomial to
another
(e) Overload the addition assignment operator (+=), subtraction
assignment operator (-=), and multiplication assignment operator(*=).

I'm going crazy here. Please help.

Do you have a file called C:\Documents and Settings\Owner\Polynomial.h ?

If not, put the stuff between #ifdef and #endif into it, inclusive.

I'm going crazy here. Please help.

Your next tip is to form a study group with your classmates.

You're missing the file [Polynomial.h].

The assignment seems to be to create that file.

And possibly also an implementation file [Polynomial.cpp].

The question is:

Using C++ language to complete this homework

Your assignment really has nothing to do with the error message. Read it.
It says it can't find the file "Polynomial.h". If that file exists, is it
in the correct directory? Is it spelled correctly? Does your compiler know
where to look for it? You may need to add it to your project, or add the
directory where it is stored to some kind of search path in your compiler or
project settings.

Answers to problems like that are best gotten from a newsgroup devoted to
your compiler, not from this language newsgroup.
