- 30. If originally x=4, what is the value of x after the evaluation of the expression: x+=x+3arrow_forwardTrue or False? The result of a logical expression cannot be assigned to an int variable.arrow_forward?Which of the following assignment statements is not correct x = ++x; x++ = y + 2; x += ++y; X = x++ + 2;arrow_forward
- Evaluate the following expressions and determine the value of allvariables, based on the above variable declarations.arrow_forwardIn Python Text-based adventure game: Pretend you are creating a text-based adventure game. At different points in the game, you want the user to select to fight, run, or hide from certain enemies. The selection variable must be sent as an argument into the choice() function. The user should enter 1 to fight, 2 to run, or 3 to hide in the main(). The choice() function should print one of the three options. Add an if statement in the choice() function to make the correct selection.arrow_forwardGiven the following declaration: int x; int* p; Which of the following expressions is allowed? Select one: a. p = x; b. p = &x; %3D C. p = *x; d. x = p;arrow_forward
- Which of the following best describes the value of the Boolean expression: a && !(b || a) The value is always true. The value is always false. The value is true when a has the value false, and is false otherwise. The value is true when b has the value false, and is false otherwise. The value is true when either a or b has the value true, and is false otherwise.arrow_forwardWhat is the value of the following expression: 9 * 2 - 8 > 5 + 2 / 2? a. False b. 10 c. True d. 6arrow_forwardQuestion: For the following code: for ( a = 1, b = 5, c = 3; a < 4; a++, b++ ) { c = a * b + c; } Indicate what values for the following variable will be when the code endsPlease check work for A = B = C =arrow_forward
- For the following code: for ( a = 1, b = 5, c = 3; a < 4; a++, b++ ) { c = a * b + c; } Indicate what values for the following variable will be when the code endsa=b=c=arrow_forwardEvaluate the following expressions, assume the following declarations: int x = 4 /3 * 2; int y = 9/ 2; int num = 6; num *= x + y; What is the value of the num after expression is evaluated?arrow_forwardHi! I am having trouble with this problem: Each week, the Pickering Trucking Company randomly selects one of its 30 employees to take a drug test. Write an application that determines which employee will be selected each week for the next 52 weeks. Use the Math.random() function to generate an employee number between 1 and 30. After each selection, display the number of the employee to test. Display four employee numbers on each line. It is important to note that if testing is random, some employees will be tested multiple times, and others might never be tested. Run the application several times until you are confident that the selection is random. Save the file as DrugTests.java. My code is on the photo. I want to add the text "Week # (insert week number here). Employee # (insert employee number here)" but I have been unsuccessful in my attempts. Any help would be great!arrow_forward
