Why can you not make a constructor as const?..

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.

then you can change its value in a function which is
