bool operator[] ( size_t pos ) const;
reference operator[] ( size_t pos );
Access bit
The function returns the value (or a reference) to the bit at position pos.
With this operator, no range check is performed. Use bitset::test to read the value with bitset bounds checked.
Parameters
- pos
- Order position of the bit whose value is accessed.
Order positions are counted from the rightmost bit, which is order position 0.
size_t is an unsigned integral type.
Return value
*this
