D Programming - Bitwise Operators

The Bitwise operators supported by D language are listed in the following table. Assume variable A holds 60 and variable B holds 13, then −

Operator	Description	Example
&	Binary AND Operator copies a bit to the result if it exists in both operands.	(A & B) will give 12, Means 0000 1100.
\|	Binary OR Operator copies a bit if it exists in either operand.	(A \| B) gives 61. Means 0011 1101.
^	Binary XOR Operator copies the bit if it is set in one operand but not both.	(A ^ B) gives 49. Means 0011 0001
~	Binary Ones Complement Operator is unary and has the effect of 'flipping' bits.	(~A ) gives -61. Means 1100 0011 in 2's complement form.
<<	Binary Left Shift Operator. The left operands value is moved left by the number of bits specified by the right operand.	A << 2 give 240. Means 1111 0000
>>	Binary Right Shift Operator. The left operands value is moved right by the number of bits specified by the right operand.	A >> 2 give 15. Means 0000 1111.

Example

Try the following example to understand all the bitwise operators available in D programming language −

Live Demo

import std.stdio;

int main(string[] args) {  
   uint a = 60; /* 60 = 0011 1100 */   
   uint b = 13; /* 13 = 0000 1101 */ 
   int c = 0;  
   
   c = a & b;       /* 12 = 0000 1100 */  
   writefln("Line 1 - Value of c is %d\n", c ); 
   
   c = a | b;       /* 61 = 0011 1101 */ 
   writefln("Line 2 - Value of c is %d\n", c );
   
   c = a ^ b;       /* 49 = 0011 0001 */ 
   writefln("Line 3 - Value of c is %d\n", c ); 
   
   c = ~a;          /*-61 = 1100 0011 */ 
   writefln("Line 4 - Value of c is %d\n", c );  
   
   c = a << 2;     /* 240 = 1111 0000 */ 
   writefln("Line 5 - Value of c is %d\n", c );
   
   c = a >> 2;     /* 15 = 0000 1111 */ 
   writefln("Line 6 - Value of c is %d\n", c );
   
   return 0; 
}

When you compile and execute the above program it produces the following result −

Line 1 - Value of c is 12  

Line 2 - Value of c is 61
  
Line 3 - Value of c is 49
  
Line 4 - Value of c is -61
  
Line 5 - Value of c is 240
  
Line 6 - Value of c is 15
