Answer : none of the other answers are correct
The correct answer will be :
!x || (x && y)
Assume x and y are boolean variables that were declared and initialized correctly. Regardless of the...
Consider the following if statement, where doesSignificantWork, makesBreakthrough, and nobelPrizeCandidate are all boolean variables: if doesSignificantWork : if makesBreakthrough : nobelPrizeCandidate = True else nobelPrizeCandidate = False elif not doesSignificantWork: nobelPrizeCandidate = False (assume that doesSignificantWork and makesBreakthrough have been initialized, there is no error) First, write a simpler if statement that is equivalent to this one. Then write a single assignment statement that does the same thing. (Hint: Try to trace this piece of code with all possible initial...
Assume a column C in a correctly written truth table contains the values for a boolean expression that consists of six distinct boolean variables. Under this assumption, if C contains 7 values of true, then how many values of false are in C? 25 none of the other answers are correct 16 1 64
Assume a column C in a correctly written truth table contains the values for a boolean expression that consists of five distinct boolean variables. Under this assumption, if C contains 3 values of false, then how many values of true are in C? 29 1 64 none of the other answers are correct 16
Consider the variables x, y and z where x and y are int variables initialized to 10 and 0 respectively, and z is a double variable initialized to 6.5 What values are stored in each variable after each statement executes? Keep in mind that the statements execute in sequence. x y z y = x++ + 5; z -= ++y * x--;
ume that x and y are boolean variables and have been properly initialized. &х Which of the following always evaluates to the same variable as the expression above? a.) x b.) y
Question 29 (Mandatory) (1 point) Assume a column C in a correctly written truth table contains the values for a boolean expression that consists of six distinct boolean variables. Under this assumption, if C contains 7 values of true, then how many values of false are in C? 25 none of the other answers are correct 16 1 64
JAVA 5) What is the output of the following code? int a = 70; boolean b = false; if(a >= 70) { System.out.print(1); if(b==true) { System.out.print(2); } } else { System.out.print(3); if(b==false) { System.out.print(4); } } System.out.print(5); 6) What is the output of the code above using these initial values? int a = 43; boolean b = false; 7) The following method is SYNTACTICALLY correct (meaning it will compile). True or false? public boolean method() { int value = 5;...
Java For the following, state whether the following statement is true or false, if false explain the reason briefly and state the complete, correct statement. a) Data type boolean is compatible with, and can be converted to, any other data type. b) Java automatically converts primitive types into their class wrapper objects. c) In creating objects using default constructors, class instance variables are initialized to their default values.
1. Assume you have a Car class that declares two private instance variables, make and model. Write Java code that implements a two-parameter constructor that instantiates a Car object and initializes both of its instance variables. 2. Logically, the make and model attributes of each Car object should not change in the life of that object. a. Write Java code that declares constant make and model attributes that cannot be changed after they are initialized by a constructor. Configure your...
Question 9 X.X = X True False Question 10 The Boolean function Flx, y, z) = (y + x)(y + x)(y'+z) is equivalent to: yz y'z + xyz + xyz O y'z+xz X
