C makes it easy to shoot yourself in the foot; C++ makes it harder, but when you do it blows your whole leg off.

yeah, yeah, but it's like a skill-check you know. like a little ling-flood in zvz. if they die to that, then they are not ready to vs me in a macro-game.

'memory operations' are minimized? i am not suggesting making extra copies, but there are oh so many tools ready at hand for "avoiding copies" (references, an arsenal of pointer-types, containers, statics even). in most scenario's you easily get away by using the most trivial of tools (f.ex. a reference).

one only needs thread-safe reference-counting for the most complex of scenarios, and then std::shared_ptr / std::weak_ptr is ready at hand, which works for _any_ type.

types with baked-in reference-counting is haram. 'cloning' and 'deep-copy' is alien terminology.

So, I've been to 2 job interviews today (one for Python and one for Ruby). Both went pretty well. Now I have to make a hard decision...

Bonus, weird Ruby question from the interview:

# what will this next line of code return?
Numeric > Integer

If that were PHP it would cast them to string and do a lexicographic comparison, and return true. In Ruby my guess is whatever Ruby's equivalent is for an illegal argument exception.

If you can't tell the difference when you've just woken up, then it's not a good feature.

std::vector<int> v(100, 1);
std::vector<int> v{100, 1};

Focusing only on technical details isn't enough to be a good software engineer. Readability is also important.

What is the fastest way to do the difference between two bitwise values? Is there an operator for that?

Right now I do value1 - (value1&value2). Could also do (value1 & ~value2), I think. But both of these require two separate operations.
