I came here to say this-- for many of the questions, the answer is Undefined Behaviour.

The very 1st one-- I havent done embedded C for a long time, but the 1st thing I was taught was *not* to assume uninitialised variables would be set to 0. The author probably tested on a known safe (read lab like) system.

Indeed, this is the correct answer.

Most the questions on the page seem to be "Let's do weird crap highly dependent on the architecture/compiler, using undefined behaviour, and LOL, we can then blame C"

And not defending C here at all, moved away from it years ago. But there are better criticisms than this
