- Examine the following for loops and determine the value of ires at the end of each of the loops, and also the number of times each loop executes. (a) ires = 0; for index = -11:11 ires = ires + 1; end ires = number of times (b) ires = 0; for index = 10:-2:1 if index == 6 continue; end ires = ires + index; end ires = number of times ires = 0; for index = 10:-2:1 if index == 6 (c) break; end ires = ires + index: end ires = number of times (d) ires = 0; for indexl = 10:-2:1 for index2 = 2:2:index1 if index2 == 6 break end ires = ires + index2; end end ires = number of times (outer loop) number of times (inner loop)arrow_forwardAnswer the following sentences true or false 1. The main difference between a do-while loop and the while loop is in the do-while loop the condition is tested at the end of the loop body. 2. In while loop, if the condition is not true, then the body of a loop will not be executed, not even once. 3. If you want to print from 10, then assign the value 0 during initialization.arrow_forwardHow is the looping action of a basic loop stopped? a, It's stopped when the condition in the LOOP statement is FALSE. Answers: b. This type of loop has a predetermined number of loops to complete. c. The condition in an EXIT WHEN statement is FALSE. d. The condition in an EXIT WHEN statement is TRUE.arrow_forward
- Using code snippets briefly explain the difference between the WHILE LOOP and the DO…WHILE loop. Write the syntax of each.arrow_forwardThe Issue: You are aware that the software breaks during the 487th loop iteration. You'll have to type continue 486 times before you get to the problem if you use a breakpoint.arrow_forwardSelect the suitable answer:1.1 If a do...while structure is used:a. An infinite loop cannot take place.b. Counter-controlled iteration is not possible.c. The body of the loop will execute at least once.d. An off-by-one error cannot occur.arrow_forward
- In a loop when a condition is false you come out of the loop. However, interesting things happen when the condition is true and you remain in the loop. What kinds of interesting things happen discuss with arguments. Course: Formal Methods in Software Engineeringarrow_forwardSuppose the statement “X is an integer and X < 5” is a loop invariant at the point at which the test for termination is performed in the loop outlined below. What can be concluded about the value of X immediately after the loop is terminated?arrow_forward12. In .............., the bodies of the two loops are merged together to form a single loop provided that they do not make any references to each other. a. Loop unrolling b. Strength reduction c. Loop concatenation d. Loop jammingarrow_forward
- Explain why an algorithm with a repetition control structure with a count-controlled loop is a better choice than a repetition with an event-controlled loop for the algorithm you created in question 6.arrow_forwardA criticism of the break and continue statements is that each is unstructured. These statements can always be replaced by structured statements. Describe in general how you’d remove any break statement from a loop in a program and replace it with some structured equivalent. [Hint: The break statement leaves a loop from within the body ofthe loop. Another way to leave is by failing the loop-continuation test. Consider using in theloop-continuation test a second test that indicates “early exit because of a ‘break’ condition.”] Use the technique you developed here to remove the break statement from the program of Fig. 5.13.arrow_forwardAnswer the sentence true or false: 1. In a while loop, the body is executed if and only if the condition is true. 2. The control comes out of a loop statement when the condition given to us turns out to be true. 3. The incrementation/decrementation increases(or decreases) the counter by a set valuearrow_forward
