Im Stuck

Need help with breaking up the functions into 4 separate <.h> files.

This is what I have so far and this is the problem that I am working on



Customer Accounts


This program should be designed and written by a team of students.Here are some
suggestions :
• One student should design function main, which will call other program functions.
The remainder of the functions will be designed by other members of the team.
• The requirements of the program should be analyzed so that each student is given
about the same workload.
Write a program that uses a structure to store the following data about a customer
account :
• Name
• Address
• City, State, and ZIP
• Telephone Number
• Account Balance
• Date of Last Payment
The structure should be used to store customer account records in a file.The program
should have a menu that lets the user perform the following operations :
• Enter new records into the file
• Search for a particular customer’s record and display it
• Search for a particular customer’s record and delete it
• Search for a particular customer’s record and change it
• Display the contents of the entire file
Input Validation : When the data for a new account is entered, be sure the user enters
data for all the fields.No negative account balances should be entered

Complete the problem as stated on Page 717 #16 in your text book. However, include the following:
• Team initials - Team One (TO) and Team Two (TT). If you are assigned to do a module(s) as the 'header' file(s) (.h) then name your file YourTeamInitialsFirstNameLastNamelnitialsModuleName.h

• If you are the team lead then you will integrate all the modules with your .cpp file. Name your file Your TeamInitialsFirstNameLastNamelnitials.cpp

• Team Lead will ZIP the project and upload the zipped file. . Your program should work for no existing input file and for existing input file.

• Add 'custID' to the structure.
• The modules are the following:
o newRecord()
o searchCustByNum)
o searchCustByName()
o deleteCustByNumName()
o updateCustName()
o updateCustAddress()
o deposit Amount() - the customer deposits an amount to their account.
Verify their customer ID and name. Add the deposit amount to their
account.
o withdrawAmount()
• the customer withdraws an amount from their account. Verify their customer ID and name. Verify they have sufficient funds in their account to withdraw. If so, subtract the withdrawal amount from their account. If not, subtract the withdrawal amount plus a overdraft fee of $35 from their account.
o displayAllCust() Name the file Your TeamInitialsFirstNameLastName.zip OR YourTeamInitialsFirstNameLastNameModuleName.h
