Creating an x86 assembler program that converts an integer to a 16-bit binary string of 0's and 1's

Question

As the question suggests, I have to write a MASM program to convert an integer to binary. I have tried many different approaches, but none of them helped me at all. The fina

Answer 1

Next is an example of using "atoi" to convert the string to number, then use assembly to convert the number to binary:

#include "stdafx.h"
#include 
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{   char str[6]; // ◄■■ NUMBER IN STRING FORMAT.
    int num;    // ◄■■ NUMBER IN NUMERIC FORMAT.
    char bin[33] = "                                "; // ◄■■ BUFFER FOR ONES AND ZEROES.
    cout << "Enter a number: ";
    cin >> str;  // ◄■■ CAPTURE NUMBER AS STRING.
    num = atoi(str); // ◄■■ CONVERT STRING TO NUMBER.
    __asm { 
           mov eax, num   // ◄■■ THE NUMBER.
           lea edi, bin   // ◄■■ POINT TO VARIABLE "BIN".
           mov ecx, 32    // ◄■■ NUMBER IS 32 BITS.
        conversion:
            shl eax, 1     // ◄■■ GET LEFTMOST BIT.
            jc  bit1       // ◄■■ IF EXTRACTED BIT == 1
            mov [edi], '0'
            jmp skip
        bit1:
            mov [edi], '1'
        skip :
            inc edi   // ◄■■ NEXT POSITION IN "BIN".
            loop conversion
    }
    cout << bin;
    return 0;
}
