int main()
{
    std::bitset<4> b1(3); // [0,0,1,1]
    std::bitset<4> b2(b1);
    std::bitset<4> b3(4); // [0,1,0,0]
 
    std::cout << "b1 == b2: " << (b1 == b2) << '\n';
    std::cout << "b1 == b3: " << (b1 == b3) << '\n';
    std::cout << "b1 != b3: " << (b1 != b3) << '\n';
}

Résultat : 

b1 == b2: 1
b1 == b3: 0
b1 != b3: 1
