How do I handle errors with std::map iterators in C++11?

What are common errors when using std::map iterators in C++11?

Common errors include dereferencing invalid iterators, modifying the map while iterating, and using end iterators incorrectly.

How can I safely iterate over a std::map?

You can use a range-based for loop or store iterators in a separate container before modifying the map.

What happens if I erase an element while iterating?

Erasing an element invalidates the iterator pointing to that element. Use the return value of erase to continue safely.

Can you give an example of iterating and erasing?

Sure! Here's a simple example: for(auto it = myMap.begin(); it != myMap.end(); ) { if(it->second < 0) it = myMap.erase(it); else ++it; }
