I would guess that most beginning programmers can deftly craft a loop that outputs sequential integer values, say from 0 to 100. In fact, this is the type of code I write whenever I learn a new language. I asked myself, “Can I write a loop to output values 0 to 100?” Usually in no time, I’ve constructed such a program. Simple.

I enjoy playing number games. I’m not good at it, but I enjoy playing them. Recently such a game piqued my curiosity enough to consider it for my monthly C For Dummies exercise: 21

After a few intermediate to advanced Exercises, I decided to try something that’s a little easier this month. Still, even if you’re a pro, it helps to pull back and try something basic just to see what you can do with it.

I enjoy reading about and studying mathematics. One of my favorite books is A History of π. I’ve used this book to inspire my Pi Day (March 14) programs. It’s fascinating stuff.

This month’s Exercise may seem like a repeat of the Exercise “We Have a Winnah!” from July of 2013. It’s not.

Like many innocent and silly math games, No Nines is nerdy to play but fun to code. The game works like this:

Last month, I published a post of the classic programming chestnut, a number-guessing game. In the post, I wrote: “Variable tries is set equal to 6 because I read somewhere that it’s possible to guess a value between 1 and 100 in six or fewer tries (though I’m probably incorrect).” And, yes, I was wrong.

Recently, I wrote a utility that required the final line of text in a file to terminate with a special code. The code had to sit at the end of a line of text, not on a blank line. What I discovered is that many text files end with one or more blank lines.

I’m certain that the nerds would love debating whether the telegraph’s Morse code system was the first binary communications network. Let them do so. Still, Morse code remains a simple communications system, translating letters and numbers into dots and dashes — which you could argue are similar to ones and zeros.
