For the majority of code, even the distinction between stack allocation and totally free-shop allocation doesn’t make any difference, nevertheless the convenience and protection of vector does.

For your foundation course Base, calling code may seek to demolish derived objects by pointers to Base, including when employing a unique_ptr. If Base’s destructor see this is public and nonvirtual (the default), it could be accidentally referred to as with a pointer that truly points to the derived object, through which scenario the conduct from the tried deletion is undefined.
