Question

Found this Multimap containing pairs?, but it is not much help

How would I insert two strings into pair? Below, my two failed attempts.

multimap<string, pair<string,string> > mymm;
mymm["Alex"] = std::pair<"000","000">; //errors
mymm.insert(pair<string, pair<string, string> > 
           ("Alex", std::pair<"000","000">); // errors out as well

I am using Visual Studio 2010, 32 bit. Thanks !

Answer 1

mymm.insert(make_pair("Alex",make_pair("000","000")));

A multimap doesn’t allow lookup using operator [], since there may be more than one match.

make_pair is a convenient way to create a pair without having to specify the types explicitly. Without using make_pair, you would need to do something like this:

mymm.insert(pair<string,pair<string,string> >("Alex",pair<string,string>("000","000")));
