When there is any question if the caller or maybe the callee owns an object, leaks or premature destruction will manifest.

If your sensible pointer is usually a Shared_ptr then counsel using an area duplicate on the clever pointer and procure a pointer or reference from that as an alternative.

Even though other containers appear to be extra suited, this kind of map about his for O(log N) lookup efficiency or a list for productive insertion in the middle, a vector will often still perform much better for containers up to a few KB in dimension.

If x = x variations the value of x, folks will be surprised and lousy faults will come about (normally like leaks).
