The program should:
Accept a series of names and addresses from the console.
The user's input should be written to a text file in the CSV format described in the lecture. But, do not include the field names in the first row of the file.
Read the records from the text file and display them in a user friendly format.
Provide a menu to allow the user to either append records to the file, display the records or exit the application.
This is what I have. It compiles just fine. I can write to the file but I cannot read the file. Can someone tell me where I went wrong with the code?
