Why is there no operator [] for std :: multimap?

Question

Why is there no operator [] for std :: multimap?

In errors with multimap (the key type is std :: string) , people say: "There is no point in extracting elements from it - there are several values ​​for each index." This makes sense to me, and that is why there is equal_mode.

So why did they decide not to add the [] operator for the multimap, then?

I feel that things like myMultiMap[key] = value will be difficult to handle, but I'm really not sure about that.

Answer 1

This may be due to ambiguity, since multiMap [key] can represent many elements depending on the number of inserts with the same key.
