Ok I have followed the tutorial but I am still having problems.

The error message I get back when I try to run the program is:

See this?
ifstream myfile ("BankAccount.txt");

You're trying to create an object named myfile. But there already is an object named myfile. Objects can't share names - how would the compiler know which one you meant when you tried to use it?
