请教| ^ &在c++中是什么运算符

#include <iostream>
#include <string>
#include <bitset>
using namespace std;


void bitCalc(int a, int b, char oper)
{
    bitset<32> b1 = a;
    bitset<32> b2 = b;
    bitset<32> b3;
    switch (oper)
    {
    case '|':
        b3 = a|b;
        break;
    case '&':
        b3 = a&b;
        break;
    case '^':
        b3 = a^b;
        break;
    }
    cout<<"b1="<<b1<<" "<<b1.to_ulong()<<endl;
    cout<<"b2="<<b2<<" "<<b2.to_ulong()<<endl;
    cout<<"b3="<<b3<<" "<<b3.to_ulong()<<endl;
}

int main()
{
    bitCalc(4,6,'|');
    cout<<endl;
    bitCalc(5,7,'&');
    cout<<endl;
    bitCalc(8,9,'^');

    cin.get();
    return 0;
}

------解决方案--------------------

C/C++ code

#include <stdio.h>
int main()
{
      printf("%4d%4d%4d\n",4|6,5&7,8^9);
}
