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

Not quite the same thing, but:

#include 
#include 
#include 

int main() {
    std::array data = { 1, 2, 3 };
    std::ostream_iterator out(std::cout, " ");
    std::copy(data.begin(), data.end(), out);
    std::cout << '\n';
    return 0;
}
