char*f="char*f=%c%s%c;main(){printf(f,34,f,34,10);}%c"; f is a global pointer to the char array which contains the string "char*f=%c%s%c;main(){printf(f,34,f,34,10);}%c"
Now in main function you are printing this string with arguments 34,f,34,10. ASCII value of " is 34. ->So in f, the first %c is replaced by ". ->The next %s is replaced by string f. ->the second %c is replaced by " and ->last %c is replaced by backspace. The last %c is actually I feel not required. So the code can be: char*f="char*f=%c%s%c;main(){printf(f,34,f,34);}";main(){printf(f,34,f,34);} I hope it helps. Try to do it manually on paper. You would be able to understand it. -Piyush On Sun, Aug 28, 2011 at 11:46 AM, rahul sharma <rahul23111...@gmail.com>wrote: > plz expalin char*f=" " > > > On Aug 28, 11:12 am, Piyush Grover <piyush4u.iit...@gmail.com> wrote: > > it's a quine problem. > > > > char*f="char*f=%c%s%c; > > main(){ > > printf(f,34,f,34,10);}%c"; > > > > main() > > { > > printf(f,34,f,34,10); > > > > } > > > > I have used whitespaces to make it understand. > > > > On Sun, Aug 28, 2011 at 11:39 AM, rahul sharma <rahul23111...@gmail.com > >wrote: > > > > > > > > > > > > > > > > > program whose output is the program itself??????????????? > > > > > -- > > > You received this message because you are subscribed to the Google > Groups > > > "Algorithm Geeks" group. > > > To post to this group, send email to algogeeks@googlegroups.com. > > > To unsubscribe from this group, send email to > > > algogeeks+unsubscr...@googlegroups.com. > > > For more options, visit this group at > > >http://groups.google.com/group/algogeeks?hl=en. > > -- > You received this message because you are subscribed to the Google Groups > "Algorithm Geeks" group. > To post to this group, send email to algogeeks@googlegroups.com. > To unsubscribe from this group, send email to > algogeeks+unsubscr...@googlegroups.com. > For more options, visit this group at > http://groups.google.com/group/algogeeks?hl=en. > > -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
