As C evolved, so did the definitions for integer sizes short, int, and long. Back when I first coded C, a short was 8-bits, an int was 16-bits, and a long was 32-bits. These values aren’t the same today or even consistent across platforms. This issue is addressed in the C23 standard by using the _BitInt() data type.

Swapping values is common task in computer programming, often used when sorting. You need the value of variable a in variable b and vice-versa. A number of methods are available for swapping, most of which involve using a temporary variable to hold one of the values during the swap.

While the C language offers hexadecimal notation and output, it ignores binary. Now with the C 23 standard, binary expression and output is supported.

The C23 standard is only partially implemented on a few compilers. To ensure that you can build C23 programs, you must obtain the latest compiler version from your distro’s package manager. Even then, not all the C23 capabilities may be available.

The next C standard is established and it’s slowly being implemented. If you have the latest version of the C compiler installed on your system, you can take advantage of some of the fun and improved features of the C programming language.

I’m continually amazed when I discover some aspect of the C programming language that I’ve not encountered before. This time, the trick is how to initialize individual array elements.

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.

Scanning the digital dictionary is fun, but it’s gone on way too long! I was going to end this series with code that solves the Spelling Bee game, but decided to end things with this Lesson. This final post scans the dictionary for words that match a given clutch of characters.

Tetration is a mathematical process that generates obnoxiously huge numbers quickly. It’s exponentiation on overdrive. The concept is insane, but it’s also something you can code in C.

I introduced the pangram concept in last week’s Lesson. The code demonstrated how to locate 7-letter words where no letter repeats, based on the online game Spelling Bee. But a pangram need not be limited to just seven letters.
