Programa basado en menús para el sistema de gestión bancaria

Prerrequisito: Cambiar caso en C/C++
Declaración del problema: 
escribir un programa para construir un sistema de gestión bancaria simple usando C++ que pueda realizar las siguientes operaciones: 

1. Cuenta abierta
2. Depositar dinero
3. Retirar dinero
4. Mostrar cuenta

Enfoque: A continuación se muestra el enfoque para realizar las operaciones anteriores: 

1. Cuenta abierta: este método toma detalles del cliente como el nombre, la dirección, el tipo de cuenta, el depósito de dinero y la creación de una nueva cuenta.

// Method to Open a new account.
void Bank::open_account()
{
    // Enter Name of a Customer
    name = "xyz Gupta";

    cout << "Enter your full name: "
         << name << endl;

    // Enter City of a Customer
    address = "Banglore";
    cout << "Enter your address: "
         << address << endl;

    // Enter Type of Account(Saving or Current)
    acc_type = 'S';
    cout << "Type of account you want "
         << "to open saving(S) or Current(C): "
         << acc_type << endl;

    // Enter Amount to deposit
    balance = 8000;

    cout << "Enter the amount for deposit: "
         << balance << endl;
    cout << "Account Created Successfully";
}

2. Depósito de dinero: la función de depósito de dinero se crea para depositar dinero en la cuenta solicitando el monto por parte del cliente. 
Te pedirá el importe y lo añadirás al saldo disponible. 
Saldo total = Saldo disponible + Monto depositado

// Method to add balance in account
void Bank::deposit_money()
{
    int Amount;

    // Enter Amount to Deposit
    Amount = 9500;
    cout << "Enter How much money "
         << "you want to deposit: "
         << Amount << endl;

    // Total_Balance = Available_Balance + Amount
    balance += Amount;
    cout << "\Available Balance: "
         << balance;
}

3. Mostrar cuenta: la función Mostrar cuenta mostrará los detalles del cliente, como el nombre, la dirección, el tipo de cuenta y el saldo disponible. 

// Method to Display the details of account
void Bank::display_account()
{
    cout << "Name: " << name << endl
         << "Address: " << address << endl
         << "Type: " << acc_type << endl
         << "Balance: " << balance << endl
         << endl;
}

4. Retirar dinero: la función Retirar dinero se crea para retirar dinero de la cuenta solicitando el monto por parte del cliente. 
Te pedirá el importe y lo restará del saldo disponible. 
Saldo total = Saldo disponible – Monto de retiro

void Bank::withdraw_money()
{
    float amount;

    // Enter Amount to Withdraw
    amount = 3200;
    cout << "Enter How much money "
         << "you want to withdraw: "
         << amount << endl;

    // Total_Balance = Available_Balance - Withdrawal_Amount
    balance -= amount;
    cout << "Available balance: "
         << balance;
}

A continuación se muestra la implementación del enfoque anterior:
