I've developed a digital wallet system that enables users to transfer funds between their wallets. The account balance cannot drop below ₹ 0.00. The smallest amount that can be transferred between wallets is 0.0001. The user gets these options for each action. And the options are as follows:

Create Wallet – This option will create a wallet for the user.

Transfer Amount – This option will enable the transfer of funds from one account to the other.

Transaction History – This option will display the account statement for the specified user.

Overview – This option will display all the account numbers currently in the system. Additionally, it shows the current balances for these accounts.

Exit – The system will exit.
