What will be the output of the following

A.  2 
B.  4 
C.  8 
D.  12 
Answer» C. 8  
Explanation: ^ is the xor operator. the binary form of 4 is 0100 and that of 12 is 1100. therefore, 0100^1100 is 1000, which is equal to 8.

Which of the following expressions can be used to multiply a given number ‘a’ by 4? 
A.  a<<2 
B.  a<<4 
C.  a>>2 
D.  a>>4 
Answer» A. a<<2  
Explanation: let us consider an example wherein a=2. the binary form of 2 is 0010. when we left shift this value by 2, we get 1000, the value of which is 8. hence if we want to multiply a given number ‘a’ by 4, we can use the expression: a<<2.

What will be the output of the following

A.  true 
B.  false 
C.  error 
D.  no output 
Answer» B. false  
Explanation: the expression not(10<20) returns false. the expression not(10>30) returns true. the and operation between false and true returns false. hence the output is false.
