Attempt to change the values of enum variables may result in compile time error.

Enum variables cannot be changed once they are defined at r=++c it results a error.

Because the value of the enum variables will be as
a=0 b=1 c=2.
But as given r=++c means c=3 but c=3 can't be possible Because last value is 2.
a=0 b=1 c=2.
But as given r=++c means c=3 but c=3 can't be possible Because last value is 2.

enum is a user defined keyword which is used to hold set of constants so the variables in enum (a,b,c) can't be altered i.e r=++c (give error).

#include<iostream.h> is unvalid header in both c and c++.
And in r=++c instruction c is an enum. We can't increase enum values.
