Talk:Middle three digits

Inspiration

The idea for the task comes from this blog entry: Interesting interview question #1 by Michael Jasper. Thanks. --Paddy3118 12:41, 2 February 2013 (UTC)

Second D entry and return type

Because the middle three digits can have leading zeroes, I would think that the more natural return type would be a string rather than an int. --Paddy3118 19:18, 3 February 2013 (UTC)

I didn't write that code, but I think I can explain it. The return type is a Variant type that can represent any type. In this case it's limited to the types listed: string, char[]. So the function will return either a string or a char[] (in the form of a Variant). By looking at the returned type (peek) you can tell whether or not an error occured.
