How does the Comma Operator work
...he contrary. With a parenthesis around the list this wouldn’t work since then the compiler just sees the comma operator between two char[], which cannot be overloaded. The code intentionally first calls the operator= and then subsequently operator, for each remaining element.

Clang vs GCC - which produces faster binaries? [closed]
....
And in any case, if you deeply care about building "the best" binaries then you

What does the Visual Studio “Any CPU” target mean?
...t I'd add one thing: If you compile as Any CPU and run on an x64 platform, then you won't be able to load 32-bit DLL files, because your application wasn't started in WoW64, but those DLL files need to run there.
If you compile as x86, then the x64 system will run your application in WoW64, and you...
Polymorphism in C++

letting you write "algorithmic" code once and then apply it to many types of data

What are the differences between B trees and B+ trees?

Of course, there may be some reshuffling to ensure the tree's height is kept to a ...
