my favourite thing about C/C++ is that a variable can be both const and volatile, it makes sense when you think about it but that was an odd one to see for the first time

say you have a hardware mapped memory location, you don't want to write to it but the value might change without your input, then you use both keywords

then you const_cast them both away!

and we couldn't possibly have a different keyword mean "read-only," we have to reuse the one that already means "won't change"

eschaton posted:and we couldn't possibly have a different keyword mean "read-only," we have to reuse the one that already means "won't change" const has never meant "won't change". at best it's always meant "this particular bit of code, accessing the object through this variable, will probably not directly make it change" except you know it's going to cast away the constness/use mutable member variables/have a non-const alias. one of those things is going to happen. const is a lie. it has never meant what you want it to mean.

Chalks posted:Besides the fact that the word "constant" literally means "won't change" maybe they'd have used the word constant if they had meant constant, instead of using a vaguely similar word to indicate a vaguely similar concept? next let's discuss how dumb it is that the char type doesn't have anything to do with burning, cleaning, or fish

if you are a c++ dev applying to a c++ position then knowing that the language is full of land mines is a requirement

From a completely different perspective I considered at one point writing a paper about how, under existing constitutional doctrine relating to differing treatment of people by gender, preemptive imprisonment of assigned males would likely be justified based on the differential crime rates. EDIT1: Testosterone is a helluva drug. EDIT2: I see "Goku Haram" and hear "a yellower shade of pale."
