Memmove() functions are those functions which are used for moving changes in the 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.
