Is there a way to implement analog of Python's 'separator'.join() in C++?

Question

All I\'ve found is boost::algorithm::string::join. However, it seems like overkill to use Boost only for join. So maybe there are some time-tested recipes?

Answer 1

simply, where the type in the container is an int:

std::string s = std::accumulate(++v.begin(), v.end(), std::to_string(v[0]),
                     [](const std::string& a, int b){
                           return a + ", " + std::to_string(b);
                     });
