bool operator[]( size_t pos ) const;	(1)
reference operator[]( size_t pos );	(2)

Accesses the bit at position pos. The first version returns the value of the bit, the second version returns an object of type reference that allows modification of the value.

[edit] Parameters

pos

-

position of the bit to return

[edit] Return value

1) the value of the requested bit

2) an object of type reference with the value of the bit.
