Re: Suggested method for returning a string from a C program?

And here's mine.
 int
main(int argc, const char **argv)
{
    unsigned int n;
    scanf("%u", &n);
    printf("%u ", n);
    do {
       n = (n & 1u) ? n * 3u + 1u : n >> 1u;
       printf("%u ", n);
    } while (n != 1u);
    putchar('\n');
    return 0;
}
