Building graph with maps

map <int, int[]> miasta;
miasta[0] = { {1,2,3} };

What do I need to do If i want to make a dictionary that contains that gets int and you can assign many integers to one int because I want to make a graph in python I can just do that like this cities = {1 : {1,2,3}, 2: {1, 2, 3}} How do I do that in c++

You probably want to use something like map<int, vector<int>> or map<int, list<int>> or map<int, deque<int>> (see vector, list, and deque)

Addressing your comment you cannot directly cout a vector. You have to use a range based for-loop:

for(const auto& i: miasta[0])
    std::cout << i << " ";
