Make sure to type c++ in different files like Main.cpp, Person.cpp, Person.j, AddressBook.cpp, and AddressBook.h   This small project is geared to test your understanding of File IO. AddressBook Exception Create an AddressBookException class that you can use to throw exceptions in your address book. Your class should have a constructor that will allow you to set the particular message that corresponds to the error. You should use your custom exception class to throw an error in the findPerson method if the person being searched for cannot be found, in the getPerson method if the AddressBook is empty.

Make a C program that gets a source file name from a user. If the file does not exist, it will generate a proper error and exits. If the file exists, it also gets the name of two more files from the user, say destination1 and destination2. These files don't need to exist as they are files that need to be written to. If the files cannot be opened for writing, a proper error will be generated.     The program then reads the source file line by line. It will copy every line that has a digit in it to destination 2 and lines that have no digit in them to destination 1. Feel free to use ctype's isdigit() function to identify digit characters.   Example: If source file is: Hi My name is Veria Hello My name is John. How can I help you? I have a problem with my giga bit internet. The speed should be around 1000 but it's just 200 Sure! I can help with that. Can I have your number in case we get disconnected? Sure! My number's 647-123-1234   First file (destination 1) should be Hi My name is…
