bitset<N>& set ( );
bitset<N>& set ( size_t pos, bool val = true );
Set bits
The version with no parameters sets (to 1) all the bits in the bitset.
The parameterized version, stores val as the new value for bit at position pos.
Parameters
- pos
- Order position of the bit whose value is modified.
Order positions are counted from the rightmost bit, which is order position 0.
size_t is an unsigned integral type.
- val
- Value to store in the bit (either true or false).
Return value
*this
If pos is not a valid bit position, out_of_range is thrown.
