sorry to ask such a simple question, but....

what happens when you try to retrieve the value from a key that was never inserted into a map container?

also, if i delete a map container and all the values are pointers, will the referenced objects be deleted too?


i would just test this out normally, but i'm having 'technical issues' with my main comp and the one i'm currently using is prehistoric.


also, another Q:

somewhat concerning the assignment operator and more so with custom data structures.

in the situation of a data structure object being assigned the value of another data structure object, what would happen if the left-hand object returned a null value? what if the right-hand object was returned a null value?

sorry if i'm being too vague, i'll provide more details if necessary.
