You are writing an inventory system for a library. This program will allow the user to enter a book title, remove a book title, and view all book titles. The book titles will be stored in a vector of strings which should be defined in your main function. • In a continuous loop, give the user to the option to add a book, remove a book, view books, and quit. • If the user chooses to add a book, call a function named addBook which asks the user to enter a title and then adds it to the vector of books. After asking the user to enter a title, perform the following input validation on it: • 1. The first character should not be lowercase • 2. There should be no special characters in the title (i.e. Each character must be a letter, digit, or whitespace character). • Ask the user to enter a title until they enter a string which passes input validation. • Once the user enters a valid string: · If the string already exists in the vector, tell the user that and do nothing. • If the string is not already in the vector, add it. • If the user chooses to view books, call a function named viewBooks which prints every string in the books vector. • If the user chooses to remove a book, call a function named removeBook. In this function, ask the user to enter a title. If the title exists in the vector, remove it. If the title does not exist in the vector, tell the user that. Hint: You may want to refer to lecture 15's notes about how to remove an element from a specific index in a vector.
