A deep copy has mostly do to with pointers and dynamic memory allocations. A deep copy will copy the actual values that are pointed to. A shallow or shadow copy copies the address where the values are stored. The problem comes into play when what you really wanted was a deep copy but you actually did a shallow copy. You go an change the values in the newly copied array and you changed the value of the copied array.
Hope this helps.
