'"no 'operator++(int)' declared for postfix '++' [-fpermissive]" on enums [duplicate]

I have got the enum

enum ProgramID
{
    A = 0,
    B = 1,
    C = 2,
    MIN_PROGRAM_ID = A,
    MAX_PROGRAM_ID = C,

} CurrentProgram;

Now, I am trying to increment CurrentProgram like this: CurrentProgram++, but the compiler complains: no 'operator++(int)' declared for postfix '++' [-fpermissive]. I think there IS such an operator that increments "enums", but if there is not, how do I get the successor of one of these values?

Solution 1:[1]

No, you are wrong, there is no such operator.

To get the next one, convert your value to an int, increment it, then reinterpret_cast it back to your enum. Note that going out of bounds can eventually lead to undefined behaviour, so checks are a good idea.
