[C++] Multiple inclusion in multiple files
- by Amumu
Hi everyone,
I am making a small game.
In BattleRecord.h:
#ifndef _CHARACTER_H_
#define _CHARACTER_H_
#include "Character.h"
#endif
class BattleRecord
{
public:
Character Attacker;
Character Defender;
Status status;
int DamageDealt;
int GoldEarned;
int ExpGained;
};
In Character.h:
#ifndef _EQUIPMENT_H_
#define _EQUIPMENT_H_
#include "Equipment.h"
#endif
class BattleRecord;
class Character
{
BattleRecord AttackEnemy(Character &Enemy);
}
In BattleRecord.h:
#ifndef _CHARACTER_H_
#define _CHARACTEr_H_
#include "Character.h"
#endif
#ifndef _BATLE_RECORD_H_
#define _BATLE_RECORD_H_
#include "BattleRecord.h"
#endif
class GUI
{
public:
//GUI Methods, and two of these:
void ViewStats(Character &Player);
void Report(BattleRecord Record)
}
The problem here is, my Character.h and BattleRecord.h need to include each other, and this definitely will cause multiple redefinition problem. Therefore, I used forward declaration in Character.h by adding:
class BattleRecord;
The problem is sovled. But then, the GUI.h needs BattleRecord.h again for reporting the battle, so I have to include BattleRecord.h into the GUI.h. I also have to include the Character.h in order to pass into the ViewStat function. I got error and stuck with this up to this piont.
