revamped c++ bank project

i need to adjust the previous banking program to beable to incorperate this: enhance the Banking Software Database Application  Use classes to model all the struct/records.  Draw a simple UML showing the classes and their relations  Use Inheritance where it makes sense  You are required to encapsulate the data which means you have to put the data in private section of the class. The public functions should include common operations that you already had (like add item, delete items, display items etc.)  The class should have at least one constructor to initialize the data.  You can use the arrays that you already had, but DYNAMICALLY ALLOCATE the arrays using ‘new’ and ‘delete’.  Pick a simple Linked List code , and use it as a function to enhance your Banking Database so far. No need to rewrite the entire assignment. Just make minimal changes to use the linked list at least once. The goal is to be able to apply and use the Linked Link concept. Again, Not all arrays need to be replaced by a linked list. Just any one array, i.e. you need to use linked list once, so that you learn how to use it. It is your responsibility to manage your dynamically-allocated memory (i.e. the memory you create with the new command). Your application must release all of the memory it allocates before it quits. Failure to do so is a memory leak, which is a very serious bug. thank you :-)
