valarray::operator^=
Obtains the element-wise exclusive logical or operator (XOR) of an array with either a specified valarray or a value of the element type.
valarray<Type>& operator|=(
const valarray<Type>& _Right
);
valarray<Type>& operator|=(
const Type& _Right
);
Parameters
- _Right
The valarray or value of an element type identical to that of the operand valarray that is to be combined, element-wise, by the exclusive logical XOR with the operand valarray.
Return Value
A valarray whose elements are the element-wise, exclusive logical XOR of the operand valarray and _Right.
Remarks
The exclusive logical or, referred to as XOR, has the following semantics: Given elements e1 and e2, e1 XOR e2 is true if exactly one of the elements is true; false if both elements are false or if both elements are true.
Example
// valarray_op_exor.cpp
// compile with: /EHsc
#include <valarray>
#include <iostream>
int main( )
{
using namespace std;
int i;
valarray<int> vaL ( 10 ), vaR ( 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 operand valarray is: ( ";
for (i = 0 ; i < 10 ; i++ )
cout << vaL [ i ] << " ";
cout << ")." << endl;
cout << "The _Right valarray is: ( ";
for ( i = 0 ; i < 10 ; i++ )
cout << vaR [ i ] << " ";
cout << ")." << endl;
vaL ^= vaR;
cout << "The element-by-element result of "
<< "the bitwise XOR operator^= is the\n valarray: ( ";
for (i = 0 ; i < 10 ; i++ )
cout << vaL [ i ] << " ";
cout << ")." << endl;
}
The initial operand valarray is: ( 1 0 1 0 1 0 1 0 1 0 ).
The _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 ).
