Output:
buf1 : Where is the time?
buf2 : Where did they go?
buf3 : Why?
6 characters of buf1 and buf2 are equal
buf2 comes before buf1
buf1 comes before buf3
Copy characters from the source string into the destination string, up to
the specified number of characters.
<string.h>
char *strncpy(char *s1, const char *s2, size_t n);
s1
s2
n
Returns a pointer to the destination string.
Copies n characters from the source string to the destination string. If
the source string is less than n characters, the destination is filled with
null characters to total n characters. If n characters were copied and no
null character was found then the destination string will not be null-ter-
minated. If the strings overlap, the behavior is undefined.
