What is the Most Elegant Way to Implode a Vector of Strings?

Imploding a Vector of Strings Elegantly

This question seeks to identify the most sophisticated approach to imploding a vector of strings into a single string. The currently implemented method is as follows:

<code class="cpp">static std::string&amp; implode(const std::vector<std::string>&amp; elems, char delim, std::string&amp; s)
{
    for (std::vector<std::string>::const_iterator ii = elems.begin(); ii != elems.end(); ++ii)
    {
        s += (*ii);
        if ( ii + 1 != elems.end() ) {
            s += delim;
        }
    }

    return s;
}

static std::string implode(const std::vector<std::string>&amp; elems, char delim)
{
    std::string s;
    return implode(elems, delim, s);
}</code>

Using boost::algorithm::join

The response suggests leveraging the boost library's join function:

<code class="cpp">#include <boost/algorithm/string/join.hpp>
...
std::string joinedString = boost::algorithm::join(elems, delim);</code>

This method offers a more concise and efficient approach to string implosion.
