C++ Functional Library - bit_xor

---

Description

It is a bitwise XOR function object class and binary function object class whose call returns the result of applying the bitwise "exclusive or" operation between its two arguments (as returned by operator ^).

Declaration

Following is the declaration for std::bit_xor.

template <class T> struct bit_xor;

C++11

template <class T> struct bit_xor;

Parameters

T − It is a type of the arguments and return type of the functional call.

Return Value

none

Exceptions

noexcep − It doesn't throw any exceptions.

Example

In below example explains about std::bit_xor.

#include <iostream>     
#include <functional>   
#include <algorithm>    
#include <iterator>     

int main () {
   int flags[] = {10,20,30,40,50,60,70,80,90,100};
   int acc = std::accumulate (flags, std::end(flags), 0, std::bit_xor<int>());
   std::cout << "xor: " << acc << '\n';
   return 0;
}

Let us compile and run the above program, this will produce the following result −

xor: 14
