Polynomial Operations:

You are required to write an application that will perform polynomial operations. A polynomial is of the form

A_nXⁿ + A_n-1X^n-1+ ……+ A₁X+A₀

Where A₀, A₁, …., A_n-1, A_n are constants and X is a variable.

Write a FORTRAN application that will store polynomials and simple way for user to choose two polynomials, and perform operations using the corresponding polynomial(s).

Select and Evaluate a Polynomial, given an input value

Select and add two Polynomials and display the result polynomial

The polynomials are in an input file poly.dat – that describes 3 polynomials using the following format: (assume polynomial degree < 20).

The first line indicates the number of polynomials described in the file.

Each subsequent line describes a polynomial using pairs of integers – each pair representing a term ex: 5X³ is represented by the pair 5 3

Example poly.dat file.

3

6 3 4 1 2 0

10 12 18 6 -4 2 1 1

4 1 -20 0

This file describes 3 polynomials. The first one is 6X³ + 4X + 2, the second one is 10X¹²+ 18X⁶ – 4X² + X, and the third one is 4X – 20.

You can output a polynomial read from the file and the results of operations as follows:

10X^12 + 18X^6 - 4X^2 + X

You should store your project to your folder for this class by midnight on the due date.
