The thing about memset(), memcpy() & memove()

Came across these two pieces of advice regarding the use of these library functions in C:
  • DO use memmove() instead of memcpy() in case you're dealing with overlapping memory regions.
  • DON'T try to use memset() to initialize type int, float, or double arrays to any value other than 0.
