Question

How to use a bitwise operator to pass multiple Integer values to a function for C++

Answer 1

#include <iostream>

class Example {
public:
    static const int ONE   = 0x01;
    static const int TWO   = 0x02;
    static const int THREE = 0x04;
    static const int FOUR  = 0x08;

    static void multiValueExample(int values) {
        if ((values & ONE) == ONE) {
            std::cout << "ONE" << std::endl;
        }
        
        if ((values & TWO) == TWO) {
            std::cout << "TWO" << std::endl;
        }
    
        if ((values & THREE) == THREE) {
            std::cout << "THREE" << std::endl;
        }
        
        if ((values & FOUR) == FOUR) {
            std::cout << "FOUR" << std::endl;
        }
    }
};

int main() {
    Example::multiValueExample(Example::ONE | Example::THREE | Example::FOUR);
}

  
  
/*
run:
  
ONE
THREE
FOUR
  
*/
