Example 1: 

class IntStack
{
public:
    IntStack() : Current(Data) {}
    int ItemsInStack() const
        {
        return Current - Data;
        }
    int Top() const
        {
        assert( ItemsInStack() != 0 );
        return *Current;
        }
    void Push( int i )
        {
        assert( ItemsInStack() < Size );
        *Current++ = i;
        }
    int Pop()
        {
        assert( ItemsInStack() != 0 );
        ...
