another, strange problem with my dev on vista

[codor kim]

hello everyone, i ran into another problem with my dev c++ on vista.

i followed my book in the creation of this sample program with 3 files:

1. main:

include <cstdlib>

include <iostream>

include "sharealike.h"

using namespace std;

int main(int argc, char *argv[])
{
int DoubleCheeseburgers = 40;
EatAtJoes();
system("pause");
return exit_success;
}

---

2. sharealike.h:

include <iostream>

include <cstdlib>

using namespace std;

extern int DoubleCheeseburgers;
void EatAtJoes();

---

3. sharealike.cpp

include <cstdlib>

include <iostream>

include "sharealike.h"

using namespace std;

int DoubleCheeseburgers;
void EatAtJoes() {
cout << "how many cheeseburgers today?" << endl;
cout << DoubleCheeseburgers << endl;
}

---

supposely when i compile and run the program i should get

how many cheeseburgers today?
40

---

printed on the console. but instead i got

how many cheeseburgers today?
0

---

0? what went wrong? and i can assign 20 or any number to "int DoubleCheeseburgers" in the main file and still get 0. can you guys help me?

Personally I think your issue is with "int DoubleCheeseburgers = 40;" being private and not public. By defining it in the main{} scope, it should be limited to that. I would simply pass the value (or reference) to the EatAtJoes() function. However, it has been some time since I have do any C++ programming and could be wrong.
