Polynomial Class

Challenge

An expression like $5x^{4}$ + $2x^{3}$ + $7x^{2}$ + $10x$ – $8$ is called a Polynomial. Write a program that creates a polynomial class called poly and implement addition of two such polynomials.

This class contains a structure called a term. This structure stores the coefficient, coeff, and exponent, exp, of the term of a polynomial. The data member noofterms stores the total number of terms that an object of the poly class is supposed to hold.

Note: It is assumed that the exponent of each successive term is less than that of the previous term.

Sample run

First polynomial:
1x^7 + 2x^6 + 3x^5 + 4x^4 + 5x^2 
Second polynomial:
1x^4 + 1x^3 + 1x^2 + 1x^1 + 2
Resultant polynomial:
1x^7 + 2x^6 + 3x^5 + 5x^4 + 1x^3 + 6x^2 + 1x^1 + 2
