You need to learn about prototypes.  The prototype for `memmove'
is in string.h, so put

    #include <string.h>

at the beginning of the file.  The function `v' is your own, so put
a prototype for it at the beginning of the file:

    int v(void);

(Or just put the function `v' before the function that uses it.)
