Simple implementation of Linux ATM self-defined teller machine

The first is implemented in the Linux underground, creating four files, the main implementation process:

Register-Login-deposit-withdraw-transfer-Change password-check personal information-Show all accounts-exit system

Don't say much nonsense, look directly at the code:
