Bank Management System using Class & inheritance in C++

The program is a Bank Management System implemented using class and inheritance in C++. The program defines two types of accounts: saving account and current account. The user is prompted to enter the account type, and based on the input, the program creates an object of the corresponding class.

The account class is the base class, and it has three private member variables: name, accno, and atype. It contains two member functions: getAccountDetails() to get the account details from the user and displayDetails() to display the account details.

The current_account class and saving_account class both inherit from the account class. They have their own private member variables: balance and sav_balance, respectively, and their own member functions: c_deposit(),c_withdraw(),c_display(),s_deposit(),s_withdraw(), and s_display() for performing deposit, withdrawal, and balance checking operations for the current account and saving account.

The program prompts the user to enter their choice of operation to be performed on the account, and then calls the corresponding member function of the respective account object based on the user input. Finally, the program exits after thanking the user for banking with them.

The program uses switch statements for user choice inputs, while loops to keep prompting the user until they choose to exit, and the goto statement to exit the program when the user chooses the "Exit" option.
