Your task is to complete a program that is capable of writing data from Contact class objects to a file on disk, and then reading them back when the program starts. To do this, you'll have to do the following:
- Use your own Contact class from previous homework
- Choose a filename, and check to see if the file exists.
- If the file exists, read the contents and then display them to the user.
- If the file does not exist, simply begin a loop to get new contact information from the user.
- In your loop to get new contact information, you should use an array to store each Contact object that the user creates, until the user says they are done.
- When the user says they are done entering contacts, write them to disk at the file name you chose and then exit the program.
