Sometimes you will also encounter Std:vector and turn std:string each other in the case of conversion.

First look at vector<char> how to turn a string:

STD:: vector<char>*data = Response->getresponsedata ();STD::stringRes//Method one for(inti =0; I<data->size (); ++i) {res+= (*data) [i];} res+=' + ';STD:cout<< Res;//Method twoSTD:: vector<char>*data = Response->getresponsedata ();STD::stringRes;res.insert (Res.begin (), Data->begin (), Data->end ());STD::cout<< Res;//Method threeSTD:: vector<char>*data = Response->getresponsedata ();STD::stringResConst Char* s = & (*data->begin ()); res =STD::string(s, data->size ());STD::cout<< Res;//Method fourstringCH ="What a fucking day!"; vector <char>Ta;ta.resize (Ch.size ()); Ta.assign (Ch.begin (), Ch.end ());

String to vector is easier:

vector <char> ta = {‘a’, ‘b‘, ‘c‘};ch.clear();ch.assign(ta.begin(),ta.end());
