True or False: C++ uses negative values to represent "False" and positive values to represent "True". It is possible that the body of a while loop may not execute at all.

Accumulating Totals in a Loop Summary In this lab, you add a loop and the statements that make up the loop body to a Java program that is provided. When completed, the program should calculate two totals: the number of left-handed people and the number of right-handed people in your class. Your loop should execute until the user enters the character X instead of L for left-handed or R for right-handed. The inputs for this program are as follows: R, R, R, L, L, L, R, L, R, R, L, X Variables have been declared for you, and the input and output statements have been written. Instructions   Ensure the file named LeftOrRight.java is open. Write a loop and a loop body that allows you to calculate a total of left-handed and right-handed people in your class. Execute the program by clicking Run and using the data listed above and verify that the output is correct.

PrimeAA.java Write a program that will tell a user if their number is prime or not. Your code will need to run in a loop (possibly many loops) so that the user can continue to check numbers. A prime is a number that is only divisible by itself and the number 1. This means your code should loop through each value between 1 and the number entered to see if it’s a divisor. If you only check for a small handful of numbers (such as 2, 3, and 5), you will lose most of the credit for this project. Include a try/catch to catch input mismatches and include a custom exception to catch negative values. If the user enters 0, the program should end. Not only will you tell the user if their number is prime or not, you must also print the divisors to the screen (if they exist) on the same line as shown below AND give a count of how many divisors there are. See examples below. Your program should run the test case exactly as it appears below, and should work on any other case in general. Output…

5. What will be the value of x after the following loop is executed? X = 0 For i = 1 To 2 For j = 1 To 3 X = X +i* j Next j Next i

Answer True or False _____ 1. It is possible that the body of a while loop might not execute at all. _____ 2. Control structures alter the normal flow of control. _____ 3. The result of a logical expression cannot be assigned to an int variable. _____ 4. Every if statement must have a corresponding else. _____ 5. The expression ! (x > 0) is true only if x is a negative number. _____ 6. The while loop: j = 0; while (j <= 10) j++; terminates when j > 10. _____ 7. A loop is a control structure that causes certain statements to execute over and over. _____ 8. When a while loop terminates, the control first goes back to the statement just before the while statement, and then the control goes to the statement immediately following the while loop. _____ 9. In a do…while loop, the condition is checked at the bottom of the loop. _____ 10. A do…while loop may never execute.

How do I write the while loop using a sentinel value to control the loop, and also write the statements that make up the body of the loop? Also including the calculations to compute the average rating.

Write a do...while loop that uses the loop control variable to take on the values 0 through 10.
