i've been trying to study for my finals by practicing classes and inheritance, this is what I've come up with so far for inheritance and such however I'm unsure how to fix the error occuring below.
#include<iostream>
#include<iomanip>
#include<cmath>
#include<string.h>
using namespace std;
//BASE CLASS DEFINITION
class hero
{
protected:
string name;
string mainAttr;
int xp;
double hp;

int range;
double attkDmg;
bool attkType;
public:
void dumpData();
void getName();

{
xp = 0;
hp = hp + (hp * 0.1);

armour = armour + ((armour*0.1) + 1);
attkDmg = attkDmg + (attkDmg * 0.05);

player.setAttkData(attribute);

system("cls");
cout << "Your hero has been created!\n\n";
player.dumpData();
system("pause");
break;
}
case 2:
system("cls");
if (heroCreated == 1)
{
cout << "Your hero has been detailed below.\n\n";
**player.dumpData(); //ERROR OCCURS HERE !**
system("pause");
}
else
{
cout <<
"You have not created a hero please exit this prompt "
"and press 1 on the menu to create a hero.";
}
break;
case 3:
system("cls");
cout << "Still Under Development";
system("pause");
break;
case 4:
system("cls");
exit = 1;
break;
default:
cout << "Your command has not been recognised, please try again.\n";
system("pause");
break;
}
}
while (exit != 1);
system("pause");
return 0;
}
void dispMenu()
{
system("cls");
cout <<
"1. Create New Hero\n"
"2. View Current Hero\n"
"3. Fight Stuff\n"
"4. Exit\n\n"
"Enter your choice: ";
}
However upon compilation I get the following errors:
220 `player' undeclared (first use this function)
Unsure exactly how to fix it as I've only recently started using OO approach. The error has a comment next to it above and is in case 2 in the main.
Cheers guys.
