15. Consider the following Java-like code: int number = <>; int mask = MASK; int result = number OP mask; if (result != 0) {       print("Bit 8 was set"); } The above code is supposed to print “Bit 8 was set” if bit 8 of user’s number was set to 1. If bit 8 was not set, then this code should not print anything (result==0). What hexadecimal value should MASK be, and what bit-wise operation should OP be, for the above code to work correctly?

Question

15. Consider the following Java-like code:

int number = <<read number from user>>;

int mask = MASK;

int result = number OP mask;

if (result != 0) {

      print("Bit 8 was set");

}

The above code is supposed to print “Bit 8 was set” if bit 8 of user’s number was set to 1. If bit 8 was not set, then this code should not print anything (result==0). What hexadecimal value should MASK be, and what bit-wise operation should OP be, for the above code to work correctly?
