==== OOPtest1.c ====
#include <iostream.h>
#include "count.h"

int main ()
{

Integer_Count intcount(5);
 
cout << endl << "Inteer Demo" << endl <<endl;
cout << "Current value:  " << intcount.get_value() << endl;

intcount.increment();
intcount.increment();


cout << "Current value:  " << intcount.get_value() << endl;

intcount.decrement();
intcount.decrement();
intcount.decrement();

cout << "Current value:  " << intcount.get_value() << endl;

intcount.reset();

cout << "Current value:  " << intcount.get_value() << endl;

cout << endl << "The end" << endl;

return 0;

}


men min compiler kommer med disse fejl og kan ikke finde ud af hvad der er galt
