C Program to print the decimal number in Binary using bit wise operators.

Algorithm:-

Step 1. Read the decimal number in a variable

             Read num

Step 2. Loop from 31 bit position to 0^th bit

             Loop i = 31 to 0

Step 3. Left shift 1 by the [i]th Index

            mask = 1 << i

Step 4. perform  ( & ) operation on the num and mask and print the results

        if (num & mask == 0)

                      print 0

          else

                      print 1

C Program:-

#include<stdio.h> 

/* program for binary reperesentation of

* Decimal Number using bitwise operators

*/ 

int main()

{

   unsigned int decimal,i = 0,mask = 1;

   printf("Enter the decimal number \n");

   scanf("%d",&decimal);

  for (i = 31;i > 0;i--)

  {

     mask = 1 << i;

    (decimal & mask)? printf("1"):printf("0");

  }

  /* for LSB Bit */

  (decimal & 1)? printf("1"):printf("0");

  printf("\n");

  

  return 0;

}
