How to display integer to binary format?

Does anyone has code on how to display an interger into its binary format? Thanks!!! :)

Code:

---

#include <iostream>
#include <stack>
#include <cstddef>

using std::cin;
using std::cout;
using std::stack;

int main()
{
    short x = -4;
    size_t i = sizeof(short) * 8; // short 的位数
  short a = 1;
    stack<short> bin;

    for ( size_t j = 0; j != i; ++j ) {
        bin.push( x & a );
        x >>= 1;
    }
    while ( !bin.empty() ) {
        cout << bin.top() ;
        bin.pop();
    }

    cout << "\nPress ENTER to quit...";
    cin.get();
    return 0;
}

Antigloss, your code is really useful! Thanks for your help! =)
