// C++ program to convert decimal to binary using array
#include <iostream>
using namespace std;

// The main function of the program
int main()
{
    // Step-1 Declare variables
    int num, binary[32], index = 0;

    // Step-2 Input decimal number
    cout << "Enter a decimal number: ";
    cin >> num;

    // Step-3 Convert decimal to binary using array
    while (num != 0) {
        binary[index++] = num % 2;
        num /= 2;
    }

    // Step-4 Output the binary number in reverse
    cout << "Binary representation: ";
    for (int i = index - 1; i >= 0; i--) {
        cout << binary[i];
    }

    cout << endl;
    return 0;
