Kirat[ad_1] Well you are declaring an array of 20 vectors. So right way would be D[1].push_back(make_pair(0,make_pair(1,2)); int a = D[1][0].first; pair<int,int> b = D[1][0].second; b.second++; // You now have a pair containing increased value. Original remains unchanged. int z = D[1][0].second.second; // contains the nested pair’s second value If you want to increase the second … Read more

[ad_1] As @Robby Cornelissen has said, you are wrapping your array in another array, which is unnecessary and breaking your code. Your for loop only iterates over a single element in the outer array.
