1.Write a program that reads a file and builds a list. After the list is built, display it on the monitor. You may use any appropriate data structure, but it should have a key field and data. Two possibilities are a list of your favorite CDs or your friends telephone numbers. Use a linked list implementation. 2.After the program above, modify it. After you create the file, the program should present the user with a menu to insert new data, remove existing data, or print a list of all data.
