C++ Functional Library - bit_and
Description
It is a bitwise AND function object class and binary function object class whose call returns the result of applying the bitwise "and" operation between its two arguments (as returned by operator &).
Declaration
Following is the declaration for std::bit_and.
template <class T> struct bit_and;
C++11
template <class T> struct bit_and;
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_and.
#include <iostream> #include <functional> #include <algorithm> #include <iterator> int main () { int values[] = {1000,2000,3000,4000,5000}; int masks[] = {0xf,0xf,0xf,255,255}; int results[5]; std::transform (values, std::end(values), masks, results, std::bit_and<int>()); std::cout << "results:"; for (const int& x: results) std::cout << ' ' << x; std::cout << '\n'; return 0; }
Let us compile and run the above program, this will produce the following result −
