3. Create a new View class that is responsible for interacting with the user. The view class will contain .a member function for displaying the main menu and reading the user's selection .a member function for reading all information from the user about one book .a member function for printing out the library; this function will take the library as a parameter, and it will use delegation, as seen in Tutorial #3, to ask the Library class to print to the screen Except for printing the library at the end of the program, only the view class will interact with the user. You must change the program so that user I/O goes through this class. After the control and view classes are correctly implemented, your code should have no global functions other than main() 4. Change the main) function so that its only responsibility is to declare a Control object and call its launch) function. 5. Create a new control class in the program to implement the control flow from the main function The Control class will contain: . a data member for the Library object that used to be declared in main) a data member for a new view object that will be responsible for user l/O .a launch member function that implements the program control flow and does the following: use the view object to display the main menu and read the user's selection, until the user chooses to exit if required by the user, create a new Book object and add it to the library using existing functions o o use the view object to print the content of the library to the screen at the end of the program The control class will perform all user I/O using the view class. wl not interact with the user directly. 3.
