How to beautifully output vector elements to the console / just to the stream in C++?

Question

C++ / C#

A banal task, implemented a million times, but always, in my opinion, somehow not very beautiful.
There is a container, a couple of iterators, just an array, or something else like that.
It is necessary to display the values ​​somewhere through the separator, so that it is only between the values.
There are all sorts of options - with a check on whether this is the first element, or the last element. I even saw such an exotic one, with the slaughter of the last comma:

template <typename container>
void print(const container& c)
{
  std::cout << "(";
  std::copy(begin(c), end(c), std::ostream_iterator<container::value_type>(std::cout, ", "));
  std::cout << "\b\b)" << std::endl;
}

Probably the most acceptable would be

if (c.size() > 0 ) std::cout << c[0];
for (auto i = begin(c) + 1; i != end(c); ++i) std::cout << ", " << *i;

But suddenly someone will tell you something from their experience

Answer 2

template <typename container>
void print(const container& c)
{
  auto it = begin(c);
  while(it != end(c) && cout << *it++, it != end(c)) { cout << ", "; }
}
