#a is the replacement sequence which is substituted in the printf statement
The statements
#define power(a) #a
printf("%d",power(a));
is substituted as
printf("%d","a");
it is replaced with the string literal "a" . then *power(a) is converted as
value at that string literal address.
Hope this solves the problem :)
