Ohad Asor of Tauchain/IDNI pretending he is C++ god.

This Ohad Asor guy claims to be a C++ expert with many years experience.

<naturalog> according to the standard, move() should leave a standard container empty

Ohad thinks move() moves the  removes elements to leave the container empty ?

when https://wandbox.org/permlink/trRijKZyq6XvZeLR clearly shows it doesn't

using namespace std;

class Data {
public:
    Data(const std::vector<int>& data): m_data(data) {}

    size_t size() const { return m_data.size(); }

private:
    std::vector<int> m_data;

};

int main() {
    std::vector<int> a = {1, 2, 3, 4, 5};

    std::cout << "a before: " << a.size() << std::endl;
    auto b = Data(std::move(a));
    std::cout << "a after: " << a.size() << std::endl;
    std::cout << "b: " << b.size() << std::endl;

    return 0;
}

./a.out


a before: 5
a after: 5
b: 5



So Ohad decided it was a bug in the C++ compiler that would make the a.size() stay the same!   Yes, of course deny deny.  HE BLAMED THE C++ COMPILER!

I have written few as 20,000 lines of C++ over the years and *I* knew better.

When I quoted https://en.cppreference.com/w/cpp/utility/move he told me i was wrong.. lol (maybe his anger that i wont kiss his ass is what blinds him)


The only thing worse than his incompetance would be his ego/arrogance [that makes him blame the compiler].
