How to print value of a hash map according to increasing/decreasing order of key in c++? -

-

if have map,

map <int,int> m;

and following key value pair (-2,3) , (-14,8) , (4,8), (6,12) , (3,76)

now if want print value in increasing order of keys,then how print ?

o/p

the keys in std::map ordered default (using operator<). can iterate on map:

for (std::map<int, int>::iterator = m.begin(); != m.end(); i++) {     cout << i->second << "\n"; }
