"Tombstones" and the lock-and-key method can be used to avoid errors caused by these objects. During deserialization, data elements can be converted to them in a process called "swizzling." "Smart" ones make garbage collecting easier by using methods like reference counting, while segmentation faults are often caused by "wild" or "dangling" ones. Accessing the value held in these objects is known as "dereferencing" them. In C and C++, they are denoted by an asterisk. For 10 points, name these data structures which hold memory addresses.
