c++ - How to nicely output a list of separated strings? -

usually, when had display list of separated strings, doing like:

using namespace std; vector<string> mylist; // lets consider has 3 elements : apple, banana , orange.  (vector<string>::iterator item = mylist.begin(); item != mylist.end(); ++item) {   if (item == mylist.begin())   {     cout << *item;   } else   {     cout << ", " << *item;   } } 

which outputs:

apple, banana, orange 

i discovered std::ostream_iterator if found nice use.

however following code:

copy(mylist.begin(), mylist.end(), ostream_iterator<string>(cout, ", ")); 

if get:

apple, banana, orange,  

almost perfect, except ,. there elegant way handle special "first (or last) element case" , have same output first code, without "complexity" ?

although not std:

cout << boost::algorithm::join(mylist, ", "); 

edit: no problem:

cout << boost::algorithm::join(mylist |      boost::adaptors::transformed(boost::lexical_cast<string,int>), ", " );
