Answer / c++ coder
Output will be 4 only.
since the argument is not passed by reference so a local
copy of m is used in the function call which is local to
mystery() it will not have any impact on the variable m
which is used in main() function.

Answer / rahul darekar
since in c lang we have to define fun first before we use it
but in this program fun mystery() in not defined and still
it is called so it will give error.
