std::vector to string with custom delimiter

Question

I would like to copy the contents of a vector to one long string with a custom delimiter. So far, I\'ve tried:

// .h
string getLabe         


        

Answer 1

Use delimiter.c_str() as the delimiter:

copy(x.begin(),x.end(), ostream_iterator(s,delimiter.c_str()));

That way, you get a const char* pointing to the string, which is what ostream_operator expects from your std::string.
