You have been asked to write a program to organize accounts in a bank. Suppose all the accounts are stored in a data file called account.dat. Your program should read in the information from this data file and then provide on-line instructions for a user's transactions including withdraw, deposit, and check balance. Your program should also allow users to create a new account for a new customer. Finally, your program should save the updated information to an output file called updated_account.dat.
You should use a class to store the information for each customer, which contains
private data members:
Birth_date (data type: a struct)
Name (data type: a struct)
Balance_saving ( data type: float)
Balance_checking (data type: float)
public data members
void withdraw( float amount, int account_type);
void deposit (float amount, int account_type);
void check_balance( ); // print out the balance on screen
customer( ); // default constructor
customer(Date birth_date, Name name, float initial_saving, float initial_checking); // parameterized constructor
The record for birth date should contain the following information:
Day (data type: integer)
Month (data type: integer)
Year (data type: integer)
The record for customers' name should contain
First_name (data type: string)
Middle_name (data type: string)
Last_name (data type: string)
The customer's name is followed by balances in saving and checking accounts.
A typical input data file looks like:
1 8 1943
Margaret Dana Mitchell
1000.00
5000.00
1 12 1955
Mario C. Puzo
9930.00
0.00
An array of class should be used to hold the information of all the accounts in the data file.
When your program writes the information of updated accounts to the output file, you don't need to sort them. However, you need to include any new account that was created interactively by using your program.
Hints:
What you need to do is to read in all the information in the data file and assign the information to a Customer array. Each array element is one customer, and each customer has the information of Birth Date, Name, and balances. In this question, you are not requested to create an account number for each customer. You may do so if you like. But, it is not required. When you access a customer, you may use birth date or name as a search key to find the record in the Customer array. Essentially, you just do a for loop through all the customers and find a match of the key to locate that particular customer.
