Chapter 10.2, Problem 21STE

Give a definition for the function with the following function declaration. The class BankAccount is defined in Display 10.5.

BankAccount newAccount(BankAccount oldAccount); //Precondition: oldAccount has previously been given a value //(that is, its member variables have been given values). //Returns the value for a new account that has a balance of zero //and the same interest rate as the oldAccount.

For example, after this function is defined, a program could contain the following:

BankAccount account3, account4; account3.set(999, 99, 5.5); account4 = newAccount(account3); account4.output(cout);

This would produce the following output:

Account balance $0.00 Interest rate 5.50%
