C++ cout auto separator

Question

I am wondering if there is way that std::cout automatically will insert some predefined value between printed sequences.

For example:

st         


        

Answer 1

How about using the ostream_iterator

int main()
{
     std::vector data {2,3,33,45};
     std::copy(std::begin(data), std::end(data),
               std::ostream_iterator(std::cout, " "));
     std::cout << "\n";
}
