Not a very tough question. Important thing to note that in
any expression pre increment operator has a higher prority
than arithemetic operator as a result value of a is
increment is first two times then value of b is evaluated.
So b = 7*7 = 14.
in first ++a we get a=6
in next ++a we get a=7
and b=7+7=14
This question will result in same output for most of the
compilers, but some rare compiler may produce an entire
diffrenent parse tree resulting in an undefined result
