As Andrey said, fold expressions can usually do. Specifically, with the
comma operator.

This is an example I usually use in training:

template <typename T, typename... Args>

void printWithSeparator(const T& sep, const Args&... args)

{

    ((cout << args << sep), ...);

}

Replace with the `(cout << args << sep)` part with what you want to do with
the arguments.
