extern struct...

Alright...I searched the boards...and thought I had found what i was looking for...but it didnt quite work...so i tried this...and tried that...still no luck...

Code:

---

//Pracitce Game
//PracGame2.cpp
#include<iostream>
#include<windows.h>
#include<string>
#include<stdlib.h>//rand()
#include<fstream>//file i/o
#include<basicf.h>//for clrscr();
#include<color.h>//for color definition
#include<time.h>//for time
#include"GMS.h"//for struct define...
using namespace std;



int main()
{
        cout<<e1->PEN_NME<<endl;
        return 0;
}


////////////////////////////GMS.h//////////////////////


//resource...
//GMS.h
#include<iostream>
#include<windows.h>
using namespace std;

struct Enemy
{
        int MX_ATT;//max attack
        int MN_ATT;//min attack
        int MX_DEF;//max defense
        int MN_DEF;//min defense
        int MX_HP;//max hp
        int MN_HP;//min hp

        int T_TRN;//total turns
        int R_TRN;//remaining turns

        char *PEN_NME;//enemy name
};

Enemy Elias;
Enemy *e1;
Elias.PEN_NME=("Elias of Lithel");
e1=&Elias;

---

All i want is to be able to define all of the variables in the structure under many different names...this is a somewhat simplified version of the code...but if someone could help I would greatly appreciate it...

Code:

---

struct foo
{
  union
  {
    int name1,name2,name3;
  };
};

---

Here, all three variable names are interchangeable.

uhm...i dont really know anything about unions...but Im not sure if I explained myself well enough...

struct Enemy; is going to have alot...and I mean alot of different definitions...and I dont want them in 'int main()'...it would be nice if I could have a seperate file for them...I tried using 'extern'...but I couldnt get it to do exactly what I needed it to...

well since no one rushed to my aid ;P (heh j/k)

Ill just go with uploading all of the enemys into a predefined number of struct pointers and what not...

thx anyways~

Maybe this is what you need? Is the problem you are having in trying to access the e1 pointer from within the main function?

Code:

---

//Pracitce Game
//PracGame2.cpp
#include<iostream>
#include<windows.h>
#include<string>
#include<cstdlib>//rand()
#include<fstream>//file i/o
#include<basicf.h>//for clrscr();
#include<color.h>//for color definition
#include<ctime>//for time
#include"GMS.h"//for struct define...
using namespace std;

extern ENEMY* e1;

int main()
{
        cout<<e1->PEN_NME<<endl;
        return 0;
}

nope didnt work =(

i mean...geez there has to be a way to do this...I just cant figure it out...thx for the try though =/

<b>edit:</b>
the pointer is now El1...because e1 is taken up doing something else now...

Try changing this:

Elias.PEN_NME=("Elias of Lithel");

To this:

Elias.PEN_NAME="Elias of Lithel";

And see how you fare.

well that did pull off one warning...but gah...still no luck!!
