  1. Suppose n is a variable of the type Byte and we wish, to check whether its fourth bit (from right) is ON or OFF. Which of the following statements will do this correctly?

    2. A. 
     if ((n&16) == 16)
 Console.WriteLine("Fourth bit is ON");
    B. 
    if ((n&8) == 8)
Console.WriteLine("Fourth bit is ON");
    C. 
     if ((n ! 8) == 8)
 Console.WriteLine("Fourth bit is ON");
    D. 
     if ((n ^ 8) == 8)
 Console.WriteLine("Fourth bit is ON");
    E. 
     if ((n ~ 8) == 8)
 Console. WriteLine("Fourth bit is ON");

    Answer : Option B

    Explanation : 

    byte myByte = 153; // In Binary = 10011001  byte n = 8; // In Binary = 00001000  (Here 1 is the 4th bit from right)  Now perform logical AND operation (n & myByte)   10011001  00001000 ---------  00001000  Here result is other than 0, so evaluated to True. ---------
    If the result is true, then we can understand that 4th bit is ON of the given data myByte.
