This month’s Exercise is to create a program that converts weight measurements by using this format:
nnnFT
Where nnn is a value, F is the unit to convert from, and T is the unit to convert to. This problem is more of an input-parsing exercise than a straight conversion.

The task for this month’s Exercise is to return the month number for a time_t value. Effectively you extract the year and month, do some math, presto. Could it be this easy?

I find it odd that the recursive solution for this month’s Exercise is far shorter than the non-recursive version. Yet, it has an elegance that’s evident in lots of recursive code examples.

The task for this month’s Exercise is to write code that outputs strings for number values, 0 through 100. Your goal is to be clever with your solution, something that took me a few versions to get correct.

The solution this month’s Exercise isn’t that complex, but it was handy in disproving a theory.

This month’s Exercise wasn’t astronomically difficult, but I did spend some time devising a solution. My goal was to try to avoid writing a nested loop. This goal proved unattainable.

The challenge for this month’s Exercise is not only to calculate Euler’s number, e, but to count how many loops a program must endure before your e value calculation matches the defined constant M_E. I hope you didn’t find this challenge too difficult.

The insidious part of this month’s Exercise is writing a function that doesn’t count a stalemate as a win. It’s what happened to me for my first draft of a solution.

The challenge for this month’s Exercise is to determine whether an integer, 1 to 100, is divisible by nine or contains the digit ‘9’. It seems like an easy puzzle for a C programmer to solve, but what I found interesting was crafting the output — specifically when a number both contains ‘9’ and is divisible by nine.

I’ve been coding hexdump utilities since the microcomputer era. They’re just so handy, especially when writing structures or other formatted data to a file. The dump assists with debugging, and it helps you figure out some undocumented data structures as well.
