bitset::reset
Resets all the bits in a bitset to 0 or resets a bit at a specified position to 0.
bitset<N>& reset( );
bitset<N>& reset(
size_t _Pos
);
Parameters
- _Pos
The position of the bit in the bitset to be reset to 0.
Return Value
A copy of the bitset for which the member function was invoked.
Remarks
The second member function throws an out_of_range exception if the position specified is greater than the size of the bitset.
Example
// bitset_reset.cpp
// compile with: /EHsc
#include <bitset>
#include <iostream>
int main( )
{
using namespace std;
bitset<5> b1 ( 13 );
cout << "The set of bits in bitset<5> b1(13) is: ( "<< b1 << " )"
<< endl;
bitset<5> b1r3;
b1r3 = b1.reset( 2 );
cout << "The collecion of bits obtained from resetting the\n"
<< " third bit of bitset b1 is: ( "<< b1r3 << " )"
<< endl;
bitset<5> b1r;
b1r = b1.reset( );
cout << "The collecion of bits obtained from resetting all\n"
<< " the elements of the bitset b1 is: ( "<< b1r << " )"
<< endl;
}
The set of bits in bitset<5> b1(13) is: ( 01101 ) The collecion of bits obtained from resetting the third bit of bitset b1 is: ( 01001 ) The collecion of bits obtained from resetting all the elements of the bitset b1 is: ( 00000 )
