what happens if we make a constructor as const
then object which is not fully constructed,
inside it you can not initialize the instance variable.

Answer / som shekhar
If the function is declared constant then you are not
intended to change the member variables of the class and if
you did the compiler throws an error.
In this case you can change the variable inside the const
function if the variable is declared as VOLATILE.
Similarly if you declare a variable as const then you cannot
change the value of the variable through its life time.
Now if you declared the constructor then you cannot
initialize the object.

Answer / som shekhar
Sorry the keyword is not volatile ,its mutable.
if the member varible of the class is declared as mutable
then you can change its value in a function which is
declared as constant.
