I came across these to statements and i am not sure how they are parsed
and the output given is produced...

printf("%d",printf("%d %d",5,5)&printf("%d %d",7,7));

o/p : 5 5 7 7 3

printf(" %d %d",printf("%d %d",7,7),printf("%d %d",5,5));

o/p : 5 5 7 7 3 3

Could some one explain where the two 3 's r obtained from.
They r not random , i think its got something to do with the length of the output
but not sure.
