Bank Database

Hey, I am in desperate need of help. I am tasked with trying to make a bank database work, and I am stuck on many things.

The project lists the following:

The banking software should have a:
1) Phase 1: Simple Command Line Interface
2) Phase 2: File Interface
3) Phase 3: Searching for a Record using Simple Sequential Search (from class)

The Command Line and File Interfaces should have the following sub-interfaces:
a) Customer Interface (this should be simple like an ATM machine interface):
a. Functions: Balance Inquiry
b. Deposit Funds
c. Withdraw funds
d. Transfer Funds to another account (like from Checking to Savings or to Credit Card)
e. Anything else that you want to add
f. Quit the application

b) Bank Employee/Teller Interface:
a. Everything in the Customer Interface, plus
b. Interface to ADD a new Customer to the Bank
c. Interface to DELETE a Customer from the Bank
d. Search for a Record based on a “Name of a Customer” (using simple Sequential Search)

c) Bank Supervisor/Manager Interface:
a. Everything in Bank Teller Interface, plus
b. Ability to List Total Number of Customers in Bank
c. Ability to List Total Amount of Money in the Bank
d. Ability to List Total Deposits in a Day
e. Ability to List Total Withdrawals in a Day
f. Ability to see/query detailed LOG of all transactions

This is what I am needed to do.

What specifically do you need help with? Tackle one thing at a time.

Well, whenever I put it the part starting at the void transfer funtion to the end, all the cout becomes ambiguous.

And I need help trying to incorporate a indata text file, such as account.txt into this code. And I need help with making a proper function of:

void transfer(int x);
void addaccount();
void deleteaccount();
void search();
void listcustomers();
void listmoney();
void listdeposits();
void listwithdrawals();
