Operator Overloading,Inheritance

Here's a simple and also a very short program in C++ that makes use of Constructors, Operator Overloading (++,--)and Single Inheritance (cause its a simple program as I mentioned it).......


/* C++ Program For Implementation Of Constructors, Operator Overloading and Inheritance */

class index
{
protected:
int count;
public:
index()
{
count = 0;
}
index(int c)
{
count = c;
}
index operator ++()
{
count++;
}
void display()
{
cout< < endl< < "count = "< < count< < endl;
}
};

class index1 : public index
{
public:
void operator --()
{
count--;
}
};

void main()
{
clrscr();
index1 i;
i++;
i++;
i.display();
i--;
i.display();
getch();
}

void main() is incorrect, it's on the FAQ of Bjarne Stroustrup's website.

main() is an integer returning function, it can cause your operating system problems if not.
