printf outdoor for

Hello, suppose me to solved it...

Code:

---

  for (i = 0; i < 4; i++)
  {
    const unsigned int id = (address >> (24 - i*8)) & 0xFF;

    sprintf(p->adr, "%u%c", id, (i == 3 ? '\n' : '.'));
  printf("%s\n", p->adr); //good 10.10.10.3
  }
  printf("%s\n", p->adr); // printed just latest value 0.0.0.3, why? me need print it not into "for" area.

---

Post the smallest compilable example that demonstrates the problem.
This is not much to work with.

because once again your sprintf starts at the beginning of the buffer not skiping the data coied there on the previous iteration of the loop

which's way I can take successful useful printf outside this loop? Hm, I think what if I'll tried usage construction strca and itoa it's not change result of printf outside of the loop.

If your for loop was as you had posted it, then the printf outside the loop would print the same as the last of the four print statements inside the loop. On the other hand, if the loop was as you had posted it, there's no way you would get "10.10.10.3" either -- you might get
10.
10.
10.
3
but each time through the loop you destroy what was previously printed.
