return dest;
}

Answer / lylez00

#include <string.h>
/* strncpy */
char *(strncpy)(char *restrict s1, const char *restrict s2,
size_t n)
{
char *dst = s1;
const char *src = s2;
/* Copy bytes, one at a time. */
while (n > 0) {
n--;
if ((*dst++ = *src++) == '\0') {
/* If we get here, we found a null character at
the end
of s2, so use memset to put null bytes at
the end of
s1. */
memset(dst, '\0', n);
break;
}
}
return s1;
