I've been away from programming for a bit, and I never really learned pointers that well.
What I'm trying to do now is code from a model.
Here's a link to the model:

My problem is that my output is not changing when I enter events.
The program is supposed to emulate a chameleon.
I just need help in understanding why it's not changing.
Thanks so much!
Here is my code:
// Assignment10.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <iostream>
#include <string>
using namespace std;
enum ChameleonState { COLD, WARM, ANGRY, ENRAPTURED };
const int tempLess = 1;
const int tempMore = 2;
const int predator = 3;
const int noPredator = 4;
const int mate = 5;
const int noMate = 6;
class Chameleon
{
public:
Chameleon()
{
state;
color;
temperature;
eventArr[tempLess] = &Chameleon::TempLess;
eventArr[tempMore] = &Chameleon::TempMore;
eventArr[predator] = &Chameleon::Predator;
eventArr[noPredator] = &Chameleon::NoPredator;
eventArr[mate] = &Chameleon::Mate;
eventArr[noMate] = &Chameleon::NoMate;
}
