// C program to convert decimal to binary using array
#include <stdio.h>

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

    // Step-2 Input a decimal number from the user
    printf("Enter a decimal number: ");
    scanf("%d", &num);

    // Step-3 Convert decimal to binary and store in array
    while(num > 0) {
        binary[i] = num % 2;
        num /= 2;
        i++;
    }

    // Step-4 Print the binary number in reverse order
    printf("Binary representation: ");
    for(int j = i - 1; j >= 0; j--) {
        printf("%d", binary[j]);
    }

    printf("\n");
    return 0;
