@amit:
*1. **printf *returns the length of the string it outputs.
i.e. printf("%d",printf("abcd")) ==> will give 4 as output.
2. Also in printf("%*s) , %**s *tells to read the precision field from the
next argument provided in printf().
Here *printf("%*s%*s",a,"",b,"") *is equivalent to* printf("%9s,%3s,"","")
.. as a=9 and b=3.*
*
*
Thus two strings of length 9 and 3 are printed. And due to the nested
printf, it returns the sum 12(9+3).
*printf("\n%d\n",printf("%9s%3s","","")); will also return 12.*
