Using pair<int, int> as key for map
c++, dictionary, std-pair
Solution
you need a pair as a key `cout << mymap[make_pair(1,2)] << endl;` What you currently have `cout << mymap[(1,2)] << endl;` is not the correct syntax.
Problem
Based on a previous question, I am trying to create a map using a pair of integers as a key i.e. `map<pair<int, int>, int>` and I've found information on how to insert: ``` #include <iostream> #include <map> using namespace std; int main () { map<pair<int, int>, int> mymap; mymap.insert(make_pair(make_pair(1,2), 3)); //edited } ``` but I can't seem to access the element! I've tried `cout << mymap[(1,2)] << endl;` but it shows an error, and I can't find information on how to access the element using the key. Am I doing something wrong?
