How to implode a vector of strings into a string (the elegant way)

Question

I'm looking for the most elegant way to implode a vector of strings into a string. Below is the solution I'm using now:

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

Is there any others out there?

Use boost::algorithm::join(..):

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