Thread: 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.

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.
