Decimal to Binary Conversion - Bitwise Right shift Operator

It is a number system conversion from decimal value into binary bits is carried out using bitwise >> (right-shift) operator.

The Right shift operator moves the bit position of a integer towards right direction. it removes bits from LSB (least significant bit) and add bits (0s) into MSB (most significant bit) and the number bits to remove and to add depends on a operand value next to the right shift operator.

      For example,  the integer variable x=10 , move 1 bit using right-shift
                    
                        binary 8-bits  x  = 00001010 
                                       x = x >> 1   move 1 bit 
                       (remove one bit from LSB (0) and  add one bit (0) into MSB 
   
                        binary 8-bits  x  = 00000101                                                
  
                        and x's decimal value becomes 5.                        
  

Decimal to binary conversion using Bitwise Right-shift Operator - algorithm

Declaration
Input	Read integer decval
Output	char bits[9]
Temp var	integer n=0
Loop	decval not equal zero
	bits[n] = decval AND 1 then '1' else '0'
	decval right shift by 1
	n=n+1
End Loop
Output	print,bits

Decimal into Binary using Right shift operator - Java code

The C program converts a decimal value into binary bits using bitwise << (right-shift) operator. It has given a decimal value as inputs and returns binary bits as its output.

 

#include <stdio.h>
#include <string.h>

int main() {


   int decval;
   char bits[9]; int n=0;
   
   printf ("\n Bitwise Right shift Operator Binary Conversion");
   
   printf("\n Enter a Decimal value" );
   scanf("%d", &decval);
   
   while ( decval !=0 ) {   
       bits[n]=( decval & 1 ) ==1 ? '1' :'0';
       decval = decval >>1;    
    n++;
   }
   bits[n] ='\0';
   

   printf( "Binary bits :%s",strrev(bits));
   return 0;
}
