This is a C++ banking system that allows customers to create bank accounts, perform deposits, withdrawals, and transfers between accounts. The system also integrates ATM functionalities and maintains customer account records.

• ✅ Customer Account Management → Create and manage bank accounts with customer details.
• ✅ Deposit Money → Add money to a specific bank account by specifying the amount.
• ✅ Withdraw Money → Deduct money from a bank account while ensuring sufficient balance is available.
• ✅ Money Transfer → Transfer money between two different accounts after validating the balance.
• ✅ ATM Functionality → Customers can check their account balance using ATM system functionality.
• ✅ Friend Functions & Classes → Implements friend functions and class relationships for controlled access to private members of classes.

• C++ (Object-Oriented Programming concepts)
• Friend Functions & Classes
• Static Methods
• User Input Handling
