Are you typing up these responses in another program then copy-pasting? You don't need to do that, it adds pointless extra linebreaks. The text will wrap by itself when it needs to.

The performance difference between a function pointer and if/else is not going to be significant here, use whatever is clearest. If it was a choice between three or more functions, a function pointer might be more efficient and elegant.

ost::MapIndex(3)					     Library Functions Manual						  ost::MapIndex(3)

NAME
ost::MapIndex - The MapIndex allows linear access into a MapTable, that otherwise could have its elements being retrieved only by key. SYNOPSIS
#include <object.h> Public Member Functions MapIndex () Creates an empty map index (pointing to nothing). MapIndex (MapObject *theObject) Creates a map index pointing to a specific map object. MapIndex (const MapIndex &theIndex) Creates a copy of a given map index. void * operator* () const Dereference operator: the pointed object it is returned as void * for easy re-cast. MapIndex & operator= (MapObject *theObject) Assignment operator to avoid implicit cast. MapIndex & operator++ () Prefix increment operator, to be used in loops and such. MapIndex operator++ (int) Postfix increment operator, to be used in loops and such. bool operator== (const MapIndex &theIndex) const Comparison operator, between two MapIndex's. bool operator!= (const MapIndex &theIndex) const bool operator== (const MapObject *theObject) const Comparison operator, between the MapIndex and a MapObject, useful to avoid casts for sake of clearness. bool operator!= (const MapObject *theObject) const Detailed Description The MapIndex allows linear access into a MapTable, that otherwise could have its elements being retrieved only by key. It can be increased, checked and dereferenced like a pointer, by means of suitable operators.

Returns: pointer to indexed object. MapIndex& ost::MapIndex::operator++ () Prefix increment operator, to be used in loops and such. Returns: the object itself, as changed.
