Hi people!

I'm a beginner learning C++ via Mac Leopard. I can't run the following code because Eclipse does not recognise the global variable 'count'. Can someone advise how I can get this code to build on Eclipse?

Thanks.

#include <iostream>
using namespace std;

void func1();
void func2();

int count; // this is a global variable

int main()
{
int i; // this is a local variable

for(i = 0; i < 10; i++) {
count = i * 2;
func1();
}

return 0;
}

void func1()
{
cout << "count: " << count; // access global count
cout << '\n'; // output a newline
func2();
}

void func2()
{
int count; // this is a local variable.

for(count = 0; count < 3; count++) cout << '.';
}
