Decimal To Binary in C

#include <stdio.h>
#include <conio.h> 
void main()
{
    int n,i;
    int b[1000];
    printf("Enter an integer in decimal number system:");
    scanf("%d", &n);
    for (i=0;n>0;i++)
    {
        b[i]=n%2;
        n=n/2;
    }
    printf("%d in binary number system is:" ,n);
    for(int j=i-1;j>=0;j--)
    {
        printf("%d",b[j]);
    }
}

1. Input:
    - Read an integer `n` from the user.
2. Initialize:
    - Create an array `b` to store binary digits.
    - Initialize a counter `i` to 0.
3. Convert Decimal to Binary:
    - Repeat while `n` is greater than 0:
    - Calculate the remainder of `n` divided by 2 (`n % 2`) and store it in `b[i]`.
    - Update `n` by dividing it by 2 (`n = n / 2`).
    - Increment `i`.
4. Output:
    - Print the binary digits stored in the array `b` in reverse order (from `b[i-1]` down to `b[0]`).
