bitset::set
Sets all the bits in a bitset to 1 or sets a bit at a specified position to 1.
bitset<N>& set( );
bitset<N>& set(
size_t _Pos,
bool _Val = true
);
Parameters
_Pos
The position of the bit in the bitset to be set to assigned a value._Val
The value to be assigned to the bit at the position specified.
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_set.cpp
// compile with: /EHsc
#include <bitset>
#include <iostream>
int main( )
{
using namespace std;
bitset<5> b1 ( 6 );
cout << "The set of bits in bitset<5> b1(6) is: ( "<< b1 << " )"
<< endl;
bitset<5> b1s0;
b1s0 = b1.set( 0 );
cout << "The collecion of bits obtained from setting the\n"
<< " zeroth bit of bitset b1 is: ( "<< b1s0 << " )"
<< endl;
bitset<5> bs1;
bs1 = b1.set( );
cout << "The collecion of bits obtained from setting all the\n"
<< " elements of the bitset b1 is: ( "<< bs1 << " )"
<< endl;
}
The set of bits in bitset<5> b1(6) is: ( 00110 ) The collecion of bits obtained from setting the zeroth bit of bitset b1 is: ( 00111 ) The collecion of bits obtained from setting all the elements of the bitset b1 is: ( 11111 )
