operator^
Obtains the bitwise exclusive OR (XOR) between corresponding elements of two equally sized valarrays or between a valarray and a specified value of the element type.

const valarray<Type>& _Left,
const valarray<Type>& _Right

valarray<Type> operator^(
const valarray<Type>& _Left,
const Type& _Right
);
template<class Type>
valarray<Type> operator^(
const Type& _Left,
const valarray<Type>& _Right
);
Parameters
_Left
The first of the two valarrays whose respective elements are to be combined with the bitwise XOR or a specified value of the element type to be combined bitwise with each element of a valarray._Right
The second of the two valarrays whose respective elements are to be combined with the bitwise XOR or a specified value of the element type to be combined bitwise with each element of a valarray.
Return Value
A valarray whose elements are the element-wise combination of the bitwise XOR operation of _Left and _Right.
Remarks
A bitwise operation can only be used to manipulate bits in char and int data types and variants and not on float, double, long double, void bool or other, more complex data types.
The bitwise exclusive OR (XOR) has the following semantics: Given bits b1 and b2, b1 XOR b2 is true if exactly one of the bits is true; false if both bits are false or if both bits are true.
Example
// valarray_op_xor.cpp
// compile with: /EHsc
#include <valarray>
#include <iostream>
int main( )
{
using namespace std;
int i;
valarray<int> vaL ( 10 ), vaR ( 10 );
valarray<int> vaLAA ( 10 );
for ( i = 0 ; i < 10 ; i += 2 )
vaL [ i ] = 1;
for ( i = 1 ; i < 10 ; i += 2 )
vaL [ i ] = 0;
for ( i = 0 ; i < 10 ; i += 3 )
vaR [ i ] = i;
for ( i = 1 ; i < 10 ; i += 3 )
vaR [ i ] = i-1;
for ( i = 2 ; i < 10 ; i += 3 )
vaR [ i ] = i-1;
cout << "The initial Left valarray is: ( ";
for ( i = 0 ; i < 10 ; i++ )
cout << vaL [ i ] << " ";
cout << ")." << endl;
cout << "The initial Right valarray is: ( ";
for ( i = 0 ; i < 10 ; i++ )
cout << vaR [ i ] << " ";
cout << ")." << endl;
vaLAA = ( vaL ^ vaR );
cout << "The element-by-element result of "
<< "the bitwise XOR operator^ is the\n valarray: ( ";
for ( i = 0 ; i < 10 ; i++ )
cout << vaLAA [ i ] << " ";
cout << ")." << endl;
}
The initial Left valarray is: ( 1 0 1 0 1 0 1 0 1 0 ).
The initial Right valarray is: ( 0 0 1 3 3 4 6 6 7 9 ).
The element-by-element result of the bitwise XOR operator^ is the
valarray: ( 1 0 0 3 2 4 7 6 6 9 ).
