NA
Correct Option: C
And operator produces 1 bit if both operand are 1. Or operator produces 1 bit if any bit of the two operands in 1.
output: 8 8

{
public static void main(String args[])
{
int a;
a = 100;
a = a >> 1;
System.out.println(a);
}

NA
Correct Option: E
Right shift operator, >>, devides the value by 2.
output: 50

- What is the output of this program?
public class Bitwise_Operator
{

NA
Correct Option: A
Unary not operator, ~, inverts all of the bits of its operand. 30 in binary is 00011110 in using ~ operator on num1 and assigning it to num2 we get inverted value of 30 i:e 11100001 which is -31 in decimal.
output: 30 -31
