Question

What’s the recommended way to convert a string to an array? I’m looking for something like:

template<class T, size_t N, class V>
std::array<T, N> to_array(const V& v)
{
    assert(v.size() == N);
    std::array<T, N> d;
    std::copy(v.begin(), v.end(), d.data());
    return d;
}

Does C++11 or Boost provide something like this? How do others do this? Seems silly having to copy/paste this function myself every time I need it in a project.

Answer 1

That seems fine. There isn’t such a thing in C++11, and I don’t think there is one in Boost either. If you don’t want to paste this all over the place, you can just put it in a header and #include that.
