STL map inside map C++
- by Prasanth Madhavan
In c++ STL map, i have a definition like
map<string, map<int, string> >;
and i iterate it using the following code.
for( map<string, map<int, string> >::iterator ii=info.begin(); ii!=info.end(); ++ii){
for(map<int, string>::iterator j=ii->second.begin(); j!=ii->second.end();++j){
cout << (*ii).first << " : " << (*j).first << " : "<< (*j).second << endl;
}
}
My doubt is is this the correct way to iterate or is there a better way to do so?
The above code works for me. But m looking for a more elegant solution.
