IP calc на с++ как реализовать вывод двоичной формы

Автор вопроса: My name is Butcher

В программе выводится ip адрес, маска, первый и последний хост, широковещательный адрес в десятичной форме, как мне реализовать вывод в двоичной форме этих элементов?

#include <iostream>

    int ResShir[8] = { 1, 1, 1, 1, 1, 1, 1, 1 };

    int Shir = 0;
    //двоичная система

    //Ввод IP-адреса и маски
    while (Success == false)
    {

Проще всего - использовать bitset. Кратенький пример:

unsigned char ip[4] = { 192, 168, 0, 0 };
for(int i = 0; i < 4; ++i)
    cout << bitset<8>(ip[i]) << " ";
cout << endl;

И еще совет - изучить битовые операции, а то такие "макароны" производят слишком тягостное впечатление...
