this code sample is taken from "A Book on C"

char s[100];

strcpy (s, "ABC");

...

the compiler issues a warning. Implicitly declaring C library function 'strcpy' with type 'char*(char *,const char *)'

Why does the compiler issue this warning, what does it mean, and what is the fix? compiler is LLVM 3.1
