Q. What's the best way to insert into an STL map?

A. Assuming these declarations:

typedef std::map<std::string, int, std::less<std::string> > StringToInt; StringToInt m;
This will usually work:
m["one"] = 1;
But this is more clear:
m.insert(StringToInt::value_type("one", 1));
It has no chance of being confused with a fetch from the map.
