How can I traverse/iterate an STL map?

Question

I want to traverse an STL map. I don\'t want to use its key. I don\'t care about the ordering, I just look for a way to access all elements it contains. How can I do this?

Answer 1

Using for with auto for C++11 and above usage

map map_variable; //you can use any data type for keys, as well as value

for(auto &x:map_variable)
{ 
    cout<

The newer format of for using auto was introduced in C++11

To give it functionality like some higher level languages like python

Where there was already an implementation of such type of iteration

P.S. : map variable keeps values sorted, so when iterating you will get keys in sorted order
