VB.Net - Bit Shift Operators

Quiz

Assume that the variable A holds 60 and variable B holds 13, then −

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

Try the following example to understand all the bitwise operators available in VB.Net −

Module BitwiseOp
   Sub Main()
      Dim a As Integer = 60       ' 60 = 0011 1100   
      Dim b As Integer = 13       ' 13 = 0000 1101
      Dim c As Integer = 0
      c = a And b       ' 12 = 0000 1100 
      Console.WriteLine("Line 1 - Value of c is {0}", c)
      c = a Or b       ' 61 = 0011 1101 
      
      Console.WriteLine("Line 2 - Value of c is {0}", c)
      c = a Xor b       ' 49 = 0011 0001 
      
      Console.WriteLine("Line 3 - Value of c is {0}", c)
      c = Not a          ' -61 = 1100 0011 
      
      Console.WriteLine("Line 4 - Value of c is {0}", c)
      c = a << 2     ' 240 = 1111 0000 
      
      Console.WriteLine("Line 5 - Value of c is {0}", c)
      c = a >> 2    ' 15 = 0000 1111 
      
      Console.WriteLine("Line 6 - Value of c is {0}", c)
      Console.ReadLine()
   End Sub
End Module

When the above code is compiled and executed, 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
