We want to create a system in C++ to manage bank accounts. A bank has many branches. Each branch has a number of associated bank accounts. There are two types of accounts: Savings and chequing accounts. A customer of a bank can have many accounts. An account must belong to one customer only.

A bank has the following attributes:

• Bank id
• Name
• Address
• Telephone number
• List of branches

Typical operations are:

• Functions that modify bank attributes except bank id
• Functions that return bank attributes (id, address, tel, number of branches, etc.)
• Add a new branch
• Delete an existing branch
• List all branches
• List accounts of a given branch
• List customers of a given branch
• Print information about a specific branch
• Print information about a specific account
• Print information about a specific customer

A branch has the following attributes:

• Branch ID
• Address
• Telephone number
• List of accounts associated with this branch

Typical operations associated with a branch are:

• Function that modify branch attributes except branch id
• Functions that return branch attributes (id, address, tel, number of accounts, etc.)
• Add a new account
• Delete an existing account
• List all accounts
• Print information about a given account
• List customers of the branch
• Return true if a given customer is a customer of this branch

An account has the following attributes:

• Account number
• Balance
• Transaction fee
• The account owner

A savings account has the following additional attributes:

• Maximum number of transactions
• Interest rate

A chequing account has the following additional attributes:

• Privilege to write cheques (a Boolean variable set to true of false depending on whether one can write cheques from this account or not)
• Overdraft limit (an amount of money a person can use when the account does not have sufficient funds)

Account typical operations are:

• Functions that modify account attributes except account id
• Functions that return attributes of an account (account id, balance, transaction fee, account owner, writing cheques, interest rate, overdraft limit, etc.)
• Add account owner
• Delete account owner
• Print information about the account owner
• Print information about an account including account id, balance, transaction fee, and owners name, account-type specific information (e.g., maximum number of transactions for a savings account)

Note: The Account class must be abstract an abstract class.

A customer has the following attributes:

• Customer ID
• First name
• Last name
• Address
• Telephone number
• Email
• List of accounts

Typical operations of Customer class:

• Functions that modify customers information except customer id
• Functions that return attributes of a customer (i.e., customer id, name, address, tel, email, number of accounts)
• Add an account
• Delete an account
• List all accounts
• List all chequing accounts
• List all savings accounts
• Etc.

Deliverables:

• Bank class
• Branch class
• Account class
• Savings account class
• Chequing account class
• Customer class
