Bank Management System using Class in C++

In this program, we are using the concept of C++ class and object, following basic operations are being performed here,

• Opening an account
• Show account info
• Deposit
• Withdraw
• Search

Note: It's a basic program just for the practice of the concept of class and object.

In this program, we have created a class Bank with the following member functions,

• OpenAccount() – It will take input account number, name and opening balance.
• ShowAccount() – It will display the account details such as account number, name and balance.
• Deposit() – It will ask for the amount to be added in available balance, and deposit the amount.
• Withdrawal() – It will ask for the amount to be withdrawn from the available, will also check the available balance, if balance is available, it will deduct the amount from the available balance.
• Search() – It will search for the record and display the account info.
