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?
There is no such an operator for enumerations. But you can write that operator yourself. For example
ProgramID operator ++( ProgramID &id, int )
{
ProgramID currentID = id;
if ( MAX_PROGRAM_ID < id + 1 ) id = MIN_PROGRAM_ID;
else id = static_cast<ProgramID>( id + 1 );
return ( currentID );
}
