In languages like C, they can be dereferenced to read the value of the data stored in memory.
In languages with garbage collection, it is impossible to create a "dangling" one by a deallocation(*) call, and when one of these is incremented past its allocated space, buffer over-runs can result. In languages like C, they can be dereferenced to read the value of the data stored in memory. For 10 points— identify this type of variable which holds an address to a space in memory rather than the value of the variable.
