free(NULL) is a no-op, this is a non-issue. I don't know what's so hard about a single if statement anyway even if this were an issue.
The video is hilarious, though:
That's a relatively new development. The cultural aspects that you're describing were already in place (entrenched) well before Reddit integrated that feature.
In the end, there is no Royal Road to learning. You have to create put in the effort to create new concepts in your head to understand something.
`-ftrivial-auto-var-init=pattern` doesn't need "erroneous behaviour" in the standard at all. In fact, it may outright conflict with it, if for example the standard defines that the compiler must initialize variables to zero instead of your chosen pattern in case of "erroneous behaviour".
"Erroneous behaviour" is a superfluous concept that exists only to allow the committee to pat themselves on the back and say "See? We no longer have undefined behaviour!".
It's like infographics. Pretty visuals, but little to no insight.
An advert is an investment: someone pays money to broadcast something and hopes that will generate awareness. Any investment is allowed to fail.
Now explain a declaration like "char *argv[]"...
> We’ve also re-set the data type such that there is no space between char and * - the data type of both of these variables is “pointer to char”, so it makes more sense to put the space before the argument name, not in the middle the data type’s name (update: it should be pointed out that this only makes sense for a single declaration. A construct like char* a, b will create a pointer to char, a, and a regular char, b).
Ah, yes, the delusional C++ formatting style. At least it's nice that the update provides the explanation why it should be avoided.
Assembly language is going to blow your mind; it lacks even more features than Go.
