The task for this month’s Exercise is to clear the screen. I pray you didn’t arrive at a solution that outputs multiple blank lines. No, you must use the ANSI codes offered in the exercise post to manipulate the cursor and wipe clean the screen. Or you could cheat, which is what I did.

This month’s Exercise is rather simple, though it doesn’t promise a simple solution. Instead, I offer three solutions. One of which is obvious and two are kind of out there. They all work, which is the point.

The challenge for this month’s Exercise is to calculate the standard deviation for a given set of data points. It’s a “whole population calculation” because all the data points are present. The trick is to follow the equation, transforming it from cryptic math mumbo-jumbo into C code.

This month’s Exercise may not have been challenging. Still, remember that blog is about learning the C language. Sometimes performing what could be a simple task may end up being complex than you anticipated.

Do you feel adequately deranged working this month’s Exercise? I’m more of a math fanboy than an expert, yet I enjoyed the process of coding a subfactorial based in the equation presented.

This month’s Exercise presents what I often refer to as a code “toggle.” Many paths lead to a solution.

This month’s Exercise is to code a function that swaps two variables. The challenge really isn’t to swap the variables, but to figure out how to code a function that does so.

Tetration is a bizarre mathematical concept. I’ve watched quite a few YouTube videos where math geeks explain the details. They venture into the terrifying territory of humongous numbers that would consume the known universe. Your programming challenge for this month’s Exercise is far less massive.

I hope you came up with an interesting solution for this month’s Exercise, one different from my own. The goal is to output unique values from zero through ten billion, values where no two digits repeat.

I hope you didn’t “flip out” over this month’s Exercise. Flipping a coin can be done by hand or by using a computer. Using a computer is easier because it can be programmed to record each flip and it saves you hand muscle molecules for flipping and the chore of writing down the results.
