LEARNING OUTCOME Part C - Encapsulation Class Basics Workshop 4: Product Upon successful completion of this workshop, you will have demonstrated the ability ? to design and code a class for a simple object to write code that includes robust user input validation, and to write code that includes formatted program output. EXERCISE Design and code a class named \texttt{Product} that holds information about a single atom. Place your class definition in a file named \texttt{Product.h} Include the following member functions in your design: ?\texttt{bool accept()} - prompts for and accepts from standard input an integer holding the product identified number, a string of no more than eight(8) characters holding the product code, a string of no more than twenty (50) characters holding the full name of the product and a floating-point value holding the product price. If any input is invalid, your function rejects that input and requests fresh data. ?\texttt{void display() const} - displays the product information on standard output. Design and code a main program that accepts information for up to 10 product elements and displays the product information in tabular format.

A univariate polynomial (i.e. a polynomial of one variable) is defined as the sum of terms of the form ax^b where a is a real coefficient, x is a variable, and b ≥ 0 is an integer exponent. Therefore, the following mathematical expressions are univariate polynomials. 4.5x^3 – 2.1x^2 + 6.2x – 9.7 -8.3x^4 + 7.6x 2.0x^2 0 The degree of a polynomial is defined as its highest-valued exponent. Hence, the degrees of the four polynomials above are 3, 4, 2, and 0, respectively. Note as well that the terms of each polynomial are sorted by decreasing exponent values. The following mathematical expressions are not univariate polynomials. The first has a negative exponent and the second is expressed in terms of two variables, x and y. x^2 + x – x^-2 9.4xy using C# The class Polynomial (Version 1) is implemented as a singly linked list of terms ordered by exponent. Each polynomial is also reduced to simplest terms, that is, only one term for a given exponent. The linked list implementation is supported by the generic Node class. public class Node { public T Item { get; set; } public Node Next { get; set; } public Node(T item, Node next) { … } (2 marks) } public class Polynomial { // A reference to the first node of a singly linked list private Node front; // Creates the polynomial 0 public Polynomial() { } (2 marks) // Inserts term t into the current polynomial in its proper order // If a term with the same exponent already exists then the two terms are added together public void AddTerm(Term t) { … } (6 marks) // Adds polynomials p and q to yield a new polynomial public static Polynomial operator +(Polynomial p, Polynomial q) { … } (4 marks) // Multiplies polynomials p and q to yield a new polynomial public static Polynomial operator *(Polynomial p, Polynomial q) { … } (5 marks) // Evaluates the current polynomial at x public double Evaluate(double x) { … } (3 marks) // Prints the current polynomial public void Print() { … } (3 marks) }
