bitset::operator^=
Performs a bitwise combination of bitsets with the exclusive OR operation.
bitset<N>& operator^=(
const bitset<N>& _Right
);
Parameters
- _Right
The bitset that is to be combined bitwise with the target bitset.
Return Value
The modified target bitset that results from the bitwise exclusive OR operation with the bitset specified as a parameter.
Remarks
Two bits combined by the exclusive OR operator return true if at least one, but not both, of the bits is true; otherwise, their combination returns false.
Bitsets must be of the same size to be combined bitwise with the exclusive OR operator by the member operator function.
Example
// bitset_op_bitwiseOR.cpp
// compile with: /EHsc
#include <bitset>
#include <iostream>
int main( )
{
using namespace std;
bitset<5> b1 ( 7 );
bitset<5> b2 ( 11 );
bitset<4> b3 ( 7 );
cout << "The target bitset b1 is: ( "<< b1 << " )." << endl;
cout << "The parameter bitset b2 is: ( "<< b2 << " )." << endl;
cout << endl;
b1 ^= b2;
cout << "After bitwise exclusive OR combination,\n"
<< " the target bitset b1 becomes: ( "<< b1 << " )."
<< endl;
// Note that the parameter-specified bitset in unchanged
cout << "The parameter bitset b2 remains: ( "<< b2 << " )."
<< endl;
// The following would cause an error because the bisets
// must be of the same size to be combined
// b1 |= b3;
}
The target bitset b1 is: ( 00111 ).
The parameter bitset b2 is: ( 01011 ).
After bitwise exclusive OR combination,
the target bitset b1 becomes: ( 01100 ).
The parameter bitset b2 remains: ( 01011 ).
