hi everbody

when i use this code in unix/windows and linux it apear in different output:
...
char* ch="12";
printf("%05s",ch);
...
in windows and unix it.ll be "00012" but in linux " 12".
if there any solution for linux to print "00012" in output?

man 3 printf

That is strange. In my Unix and OS X shells, it runs like you'd expect, but in Gentoo it uses blank padding instead of zero-padding. Check the man page, but it doesn't help too much; it clearly says that the value should be zero padded when you use %0, unless you also use the '-' flag (which you aren't).

Hmm....

Um, not so much. My man page says of the zero flag:

       0      The value should be zero padded.  For d, i, o, u, x, X, a, A, e,
              E,  f, F, g, and G conversions, the converted value is padded on
              the left with zeros rather than blanks.  If the 0  and  -  flags
              both  appear,  the  0  flag is ignored.  If a precision is given
              with a numeric conversion (d, i, o, u, x, and X), the 0 flag  is
              ignored.  For other conversions, the behavior is undefined.

Ah! I skipped past the end after I checked that 's' wasn't in that list of conversion flags. Good call.
