Translating python dictionary to C++

Question

I have python code that contains the following code.

d = {}

d[(0,0)] = 0
d[(1,2)] = 1
d[(2,1)] = 2
d[(2,3)] = 3
d[(3,2)] = 4

for (i,j) in d:
    print d[(         


        

Answer 1

The type is

std::map< std::pair, int>

The code to add entries to map is like here:

typedef  std::map< std::pair, int> container;

container m;

m[ make_pair(1,2) ] = 3; //...

for(container::iterator i = m.begin();  i != m.end(); ++i){
   std::cout << i.second << ' '; 
   // not really sure how to translate [i,j] [j,i] idiom here easily
}
