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)
How 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.
Using code snippets briefly explain the difference between the WHILE LOOP and the DO…WHILE loop. Write the syntax of each.

- The 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_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_forwardPlease put these for loop steps in the right order. Answers Code following the body of the loop is executed The counter is compared to some value to see if the necessary condition is met The counter's value is updated A counter is initialized to some starting value The code in the body of the loop gets executedarrow_forward
- A 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_forwardBecause it is repeated so many times in the code, the statement or block of an endless loop is known as an infinite loop's block.arrow_forward
- What is loop unrolling? Explain why/how loop unrolling will optimize a code segment. Give an example of a code segment that can be improved using loop unrolling, and show what the improved code would be.arrow_forward6. What is the loop control variable?

- The condition in a posttest loop can be phrased as either a looping condition or a loop exit condition.a. Trueb. Falsearrow_forwardDemonstrate a do-while loop program that asks the user to enter two numbers. The numbers should be added and the sum displayed. The loop should ask the user whether he or she wishes to perform the operation again. If so, the loop should repeat; otherwise it should terminate.arrow_forwardThanks in advance.
