Convert decimal to binary of the user's input. Only to use for loop and modulus

Question

#include<iostream>
#include<conio.h>
using namespace std;

int main()
{
int DecimalNumber;
int BinaryNumber;
cout << "Enter Your Decimal Number Here :";
cin >> DecimalNumber;
cout << endl << DecimalNumber << ": In Binary Is : ";

for (int loop = DecimalNumber;loop >= 1;loop /= 2)
{
BinaryNumber = loop % 2;
cout << BinaryNumber;
}

_getch();
return 0;

}

This code prints the answer but is inverted

Answer 1

Find largest power of 2 < DecimalNumber and divide by 2 in loop each step. Also in loop print 1 if remaining number is bigger and sutract from number, else print 0.

To find largest power of 2 you can use another loop starting at 2 and doubling each step

Answer 2

You can store your whole output in string variable, so it will be easy to reverse and print

Answer 3

Michał Doruch sorry I wasn't clear, question asks us to only use "for" loops and modulus operator. Even I don't think it would be possible but thats why I posted it here

Answer 4

Coder Kitten exactly thats why I'm here. It can be conducted easily using a pointer or array. I just want to know if it is even possible without them
