Implement class BankAcct, for Bank of USQ, using bankacct.cpp and bankacct.h:

- The BSB for Bank of USQ at Towoomba is 324-001.

- A BankAcct object will have a 3 digit bank account number larger than 100 which is a serial number generated by a Serial object. E.g. 324-001-101, 324-001-102, 324-001-103 are the first three possible bank account number for Bank of USQ.

- A BankAcct object will have a bank account pin code which is a 4 digit random number generated by a RandomInt object.

- Class BankAcct should provide a member function to screen display the bank BSB plus account number and the pin code.

Implement an application bankUSQ_app.cpp:

- It will read bankUSQ_account.txt and print out all accounts and pins from the file.

- It will ask user input for the number of bank accounts to generate, and the starting account number.

- Uses class Serial and class RandomInt to generate the account number and the pin code.

- Create BankAcct objects to hold the account number and pin code.

- The BSB (324-001) can be hard coded for screen display only. You do not need to write BSB as part of the account number in bankUSQ_account.txt.

- All generated bank accounts will be store in a vector.

- Before the application exits, it will append the generated accounts to an existing text file named bankUSQ_account.txt. You will need to create an empty bankUSQ_account.txt

before you run the application for the first time.

- Repeat the above steps until the number of bank accounts to generate is 0.

- Assume that all bank accounts generated in each call of the application are unique and not overlapping.

Use Exception to check

- The number of accounts to be created is less than 10. (Assume no negative integers entered.)

- If the input is not valid, the program will ask for user input again.

- You have to use BankError class which is derived from logic_error for exception handling.

- Implement BankError in bankUSQ_app.cpp.

Submit bankacct.cpp, bankacct.h, and bankUSQ_app.cpp and task3.txt. RandomInt class and Serial class files are the same as in Task 1 and 2.
