I watched the film Contact a few weeks ago. The movie is about first contact with an alien civilization. It’s smart cinema, which offers that communications between species would be mathematical in nature, as math is the universal language.

Planting a Binary Tree
Tree structures are yet another way to organize data. They’re similar to a linked list, but with the data organized by value into a series of branches and leaves. OMG! It’s like a tree!

Outputting a Table of Math Stuff
Though I’m admittedly not good at math (at least according to my grades in school), I enjoy playing with math stuff on the computer. Programming allows me to mess with numbers and values without the risk of that ugly red mark and the need to wonder how a D or an F on my transcript affects my overall GPA.

To #include or not to #include
I had a reader offer me a puzzle the other day. His code ran well without the #include directive and he wondered why. I did, too.

Numbers Complex and Imaginary
Your C programs aren’t meant to suffer with an inability to handle values such as the square root of -1, the imaginary number i. No, you can easily manage such mathematical mysteries, making rare the possibility of a -nan result, as shown in last week’s Lesson.

Formatting a Series for Output – Solution
The challenge for this month’s Exercise is to output a series of numbers, 1 through 10, and to ensure that the final number doesn’t look dorky. I’m certain that’s what I asked for.

The sqrt(-1.0)
The four-letter word that made me avoid computers and programming for far too long is math.

Silicon Valley Encryption, Part III
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.
