How do I get a const_iterator using auto?

Question

First question: is it possible to \"force\" a const_iterator using auto? For example:

map usa         


        

Answer 1

Sorry, but I just think the best suggestion is not using auto at all, since you want to perform a (implicitly valid) type conversion. auto is meant for deducing the exact type, which is not what you want here.

Just write it this way:

std::map::const_iterator city_it = usa.find("New York");

As correctly pointed out by MooingDuck, using type aliases can improve the readability and maintainability of your code:

typedef std::map my_map;
my_map::const_iterator city_it = usa.find("New York");
