I have unordered_map. which has client and their associated users in std::list. I can print my client, but don't know how to print its userslist.
mapType clientUserMap;
clientUserMap.insert (mapType::value_type("C1", std::list<std::string> (userlist)));
boost::unordered_map<std::string, std::list<std::string> >
::const_iterator it = clientUserMap.find("C1");
std::cout << it->first << std::endl;
It's a list, so iterate through the list and print.. e.g.
for(std::list<std::string>::const_iterator l_it = begin(it->second); l_it != end(it->second); ++l_it)
std::cout << *l_it << std::endl;
Of course there are many more fancy ways of doing this...
All you have to do is iterate over the list:
std::list<string> const &users = it->second;
std::for_each(users.begin(), users.end(), [](string const& user){std::cout << user << std::endl;}
as you already using boost, you could also use BOOST_FOREACH to iterate over the user list. The code would then look like this:
#include <boost/foreach.hpp>
...
boost::unordered_map<std::string, std::list<std::string> >
::const_iterator it = clientUserMap.find("C1");
std::cout << it->first << std::endl;
BOOST_FOREACH( std::string user, it->second )
{
std::cout << user << endl;
}
