Create a BookException class that is instantiated when a Book’s price exceeds 10 cents per page and whose constructor requires three arguments for title, price, and number of pages. Create an error message that is passed to the Exception class constructor for the Message property when a Book does not meet the price-to-pages ratio. For example, an error message: For Goodnight Moon, ratio is invalid. ...Price is $12.99 for 25 pages. Next, create a Book class that contains fields for title, author, price, and number of pages. Include properties for each field. Throw a BookException if a client program tries to construct a Book object for which the price is more than 10 cents per page. Finally, using the Book class, create an array of five Books. Prompt the user for values for each Book.

- The following class maintains an account balance and returns a special error code. public class Account { private double balance; // returns new balance or -1 if error public double deposit(double amount) { if (amount > 0) balance += amount; else return -1; // Code indicating error return balance; } } Rewrite the class so that it throws appropriate exception instead of returning -1 as an error code. Write test code that attempts to depositIn C++ You have a class called Fraction, which uses the heap. The constructor for the class is declared as: Fraction::Fraction(); Implement an exception handling design in the parameterized constructor to catch zeros in the denominator. Show the new exception class you will need to put in the header (specification) file. Show the definition for your parameterized constructor that throws the exception if the denominator is zero. Finally, show how to use the try-catch statement in the driver program when instatiating a new paramerized Fraction object.
