I am new to creating class and this is our assignment:
Change the Critter Caretaker from Chapter 8 (pgs 274-281) program:
Create an unlisted menu option that reveals the exact values of the critter's hunger and boredom levels.
This means you create an option that will be acted on from the menu list - BUT you don't display that option. It's "secret".
Make the critter more expressive about it's needs by hinting at both how hungry and bored it is. "I'm starving!", "I'm hungry", "I'm full", etc. The user should have to do nothing for the critter to express it's needs. In other words, this should not happen in response to a menu item being selected, or only when one menu item is selected.
This is the original code:

The problem im having is that it is saying that identifier m_Hunger and identifier m_Boredum are undefined Here:
1
2
3
4
|
case 4: //secret menu option that displays exact hunger and boredum levels
cout << "\nCritter Hunger Level: " << m_Hunger << ".\n";
cout << "\nCritter Boredum Level: " << m_Boredom << ".\n";
|
above here:
1
2
3
4
5
6
7
8
|
private:
int m_Hunger;
int m_Boredom;
int GetMood() const;
void PassTime(int time = 1);
};
|
i thought they were defined so i tried changing private to public and that didnt help. Im lost and could use at least a nudge in the right direction if not an explanation of what im doing wrong. Thanks.
