So every once in a while, when I read documentation for getline, I get reminded of the infamous whitespace issue. Yes, I know what it is. This question is about the supposedly standard solution
std::cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');
Meanwhile, I was always using
std::cin >> std::ws;
The difference between the two being mainly mine one does also ignore whitespace at the beginning of the line. That said, for many uses it is sufficient or equivalent, and arguably simpler to remember.
So why do people always recommend the first one? Not knowing about both? Finding those spaces precious by default?
