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
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.
