Memmove() functions are those functions which are used for moving changes in the memory,
whereas memcpy() are those which do the copying of memory.

In memmove() the source memory of specific size is copied into buffer and then moved to destination.As a result, overlapping is done successfully.
In memcpy() there is no extra buffer taken for source memory. The copying is done directly on the memory. As a result, overlapping may give unexpected results.
