How to Delete an Account from Simple Banking System Prog

[greenhorn101]

This is a working program: If you create an Account then try to create another Account, it prompts: Account Already Existing. After you close the Account, you should be able to create a new Account but instead it prompts Account Already Existing. Need assistance on the logic. Issue on the Open Account and Close Account. Thank you in advance.

[Olysold]

You reset account to 0, but,

if (open_a == 1)
   {
   	cout << "\n\n\n\n\n\t\t Invalid! Account Already Existing!";
   }

nothing is done to open_a when the user chooses to close the account.

I thought about that too.
I finally got it. Thank You for the assistance Olysold
