Answer Posted / tathagata chakraborty
None of the other answers are coming to the point of this
question.They r all wrong.
right answer is the code will crash while returning frm Add
(). bcause the function is returning a local variable of
type T i.e. a+b as a refference. u cannont return a local
variable as refference bcause that will go out of scope as
soon as the function returns.
