→Declaring an Objective-C Class Implementation
@end
</pre>
The parent class chosen above is the ''NSObject'' class. This is a standard base class provided with the Objective-C Foundation Classes and is class from which most new class are derived. By deriving BankAccount from this parent class we inherit a range of additional methods used in creating, managing and destroying instances that we would otherwise have to write ourselves.
Now that we have the outline syntax for our class, the next step is to add some instance variables to it.
