c++ : tolongin ane bitwise operator gan...

ane baru belajar c++ gan pke ebook... nah ad soal kaya gini :

Write a program that reads an integer value from the keyboard into a variable of type int , and uses one of the bitwise operators (i.e. not the % operator!) to determine the positive remainder when divided by 8. For example, 29 = (3x8)+5 and 14 = ( 2x8)+2 have positive remainder 5 and 2, respectively, when divided by 8.

ane dah dpt jawabannya dari hasil ane nyari di google :

Spoiler for code:

#include <iostream>

using std::cout;
using std::endl;
using std::cin;

int main()
{
int remainder;

cout << "Please insert number" << endl;
cin >> remainder;
cout << endl;

remainder &= 7;

cout << "Remainder : " << remainder << endl;

return 0;
}

nah tapi ane masih bingung. kok bisa tw klo hrus di &7?? masa harus dicoba satu satu angkanya? ato ad caranya biar gampang nemuinnya? ane bingung gan...(maaf klo pertanyaan ane konyol gan, baru belajar bgt) emoticon-Sorry
