Here is an issue that crops up often in programming, specifically when outputting data in a series: How do you separate items in the series and not make the last item look dorky? It’s tricky.

My attempt to de-obfuscate the easter egg from the HBO series Silicon Valley didn’t help in my efforts to reverse engineer the code. I got close, but I just can’t obtain that first (or final) value.

As a string, a phone number is easy to parse, left-to-right, as shown in last week’s Lesson. As a value, however, the processing requires mathematical manipulation to work it from left-to-right.

This Lesson’s topic is more about database programming than C programming, but the philosophy still applies. When do you store a number as a value as opposed to storing it as a string? Two famous examples are zip codes and phone numbers.
