You are to create a program that can be used for keeping track of textbooks required and recommended for classes and the cost of those textbooks. All input will be taken from standard input. Each line of input will begin with a single or double character code that identifies the type of operation that line describes. The possible line formats are: B Define a book. The ISBN is a 13 digit number. The Title is a string of arbitrary length (ending with a line break) e.g.: B 1234567890123 Programming for Programmers DSolution
