Comment by Peter - Reinstate Monica on What is the purpose of `enum class`...
So after -- what is it, four decades? -- C++ has finally caught up with Ada83's derived types! The "bare metal" crowd has a hard time coming around to built-in safety features.
View ArticleComment by Peter - Reinstate Monica on C++: Use free function as member function
@RemyLebeau Yes, on the language level; but not on the object file level, which is what the OP tries to exploit. If you knew the name mangling scheme I suppose you could write a free function (perhaps...

To me, the code looks fine, with or without casts. Looks as if gcc is mistaken. Does that only happen with three indirections?

In other words, a regression.

I'd suggest one array per character, that should make printing much easier.

For some reason, a recent msys2 mintty still interprets the lines as commands, even if pasted in quotes (after saying bind 'set enable-bracketed-paste off'). Before, it didn't paste anything and just...

On architectures that support unaligned memory access, most compilers support an option or pragma to "pack" the structure. But the usual demand is speed over space, and aligned access is usually...

@Mark Yes, the compiler should be deterministic here (and, additionally, not depend on unrelated side conditions like the time of day etc.). But the compiler is free to do things differently from case...

Concurring with @PepijnKramer here. Windows is simply not a real time operating system. That said, you may try to run a test application with real time priority to prevent other programs from...
