Answer 1

#define PRINTF "%s, Bazinga ! \n"

printf(PRINTF,PRINTF);
Above statement is same as
printf("%s, Bazinga ! \n", "%s, Bazinga ! \n");

Format specifier is used twice i.e %s

First statement will processed like this,
"%s Bazinga !
" ---> Note: ending double quote is on new line

Now, %s will be replaced by the string "%s, Bazinga ! \n"

So final output is like :
"%s, Bazinga !
,Bazinga !
"
Why %s is not replaced again?
Well that's because now it is part of string.
