C and C++ program to accept an integer and convert it into an equivalent binary

In this post I am going to publish a C++ program which will accept an integer from the user and print it's binay on the output screen. The coding of the program goes as follows :

// Program to convert an integer number into its equivalent binary
#include "iostream.h"
#include "conio.h"
#include "stdlib.h"
#include "stdio.h"
#include "string.h"
// Function to convert an integer number into binary number
void integer_to_binary(int num)
{
 long binary = 0;
 int decimal, X[10], d1, d2, q, r;
 // Convert the number into decimal
 d1 = num;
 int i = 0;
 while (d1 >= 2)
 {
  q = d1 / 2;
  r = d1 % 2;
  X[i] = r;
  d1 = q;
  if (d1 < 2)
  {
   i++;
   X[i] = d1;
  }
  else
   i++;
 }
 int j = i;
 for (i = j; i >= 0; i--)
 {
  cout << X[i];
 }
}
main()
{
 int num;
 clrscr();
 cout << "Enter any integer number ";
 cin >> num;
 integer_to_binary(num);
 return 0;
}
