Linkedlist
A user-interface which allows the user a menu of choices for a bank database application. The database contains the accountnumber, name, and address fields for each person.
Menu Options The information is stored in a database which is a black box and can only be accessed by the user interface functions.
The following menu choices must be available:
Add a new record in the database Print information about a record using the accountno as the key Print all information in the database Delete an existing record from the database using the accountno as a key Quit the program.
For this project, I gained a lot of experience with linked list in C. This was my biggest and hardest project when I practice programming in C.
