//只列举了部分常用的strcpy，strcmp，strcat，strchr，strstr，strpbrk...

char *strcpy(char *dest, const char *src)
{
char *tmp = dest;

while ((*dest++ = *src++) != '\0')
/* nothing */;
return tmp;
}

char *strncpy(char *dest, const char *src, size_t count)
{
char *tmp = dest;

while (count) {
if ((*tmp = *src) != 0)
