True or False?
In a do…while loop, the condition is checked at the bottom of the loop.
Which of the following statements is true exclusively for the while loop? Only to the do...while loop? To both of you?
It's a conditional loop, for starters.
The loop's body is executed at least once.
Before the loop is entered, the logical expression controlling the loop is evaluated.
The loop's body may or may not execute.
Which statement about counter variables used in program loops is correct?
The counter variable should be initialized as the first statement within the loop command block that will be repeatedly executed.
It is best practice for counter variables to have global scope.
The value of the counter variable changes with each iteration of the loop.
It is common for programmers to use variables named counter1, counter2, and counter3 for program loops.

Expected Output Example 1 Enter the start of the loop: Enter the limit of the loop: 25 The current value is 3 The current value is 6 The current value is 12 The current value is 24 The last value of current that was less than 25 was 24 Example 2 Enter the start of the loop: 25 Enter the limit of the loop: 102 The current value is 25 The current value is 50 The current value is 100 The last value of current that was less than 102 was 100 Specifications • You should submit a single file called M5A2.py • It should follow the submission standards outlined here: Submission Standards Your program populate an integer named start using input • Your program populate an integer named limit using input Your program must use an iterator named current Your program must move through the values using a while-loop Tips and Tricks That last…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_forwardThe term "Pre-test" means that The loop is tested after the body statements are run. OThe loop is tested after the loop is run through for the first time OThe loop will be tested before the statements to be repeated are executed, even once. OThe loop will be tested before the next iteration (after the first)arrow_forwardProblem Description: A while loop and do/while loop will repeat code while the condition is true. The basic difference is when the condition is checked. The while loop checks the condition before the loop starts or after the loop ends. A do/while loop will check the condition at the end of the loop to determine if the loop should be repeated. A do/while loop will run at least once whereas a while may be skipped entirely. while ( ) do I/ Repeated code goes here I/ Repeated code goes here while ( ); Checkpoint 1: Use a while loop to display the numbers 1 through 10. You must initialize your loop counter before the loop and increment the loop counter inside the loop. Checkpoint 2: Use a while to ask the user for a list of numbers. It is not known how many numbers the user will enter, but the last number will be -1. After all numbers have been entered, state how many numbers were put in. Checkpoint 3: Use a do/while loop to display the numbers I through 10. You must initialize your loop…arrow_forward
- in python for glass box testing of a while loop, you should test cases where: a) the while loop is not entered b) the body of the while loop is executed just once c) the body of the while loop is executed more than once e) all of these f) exiting the loop in the middle of the bodyarrow_forwardAll programming languages have a loop capability. Looping is the program logic’s ability to repeat one or more lines of code either: A set number of times, a “for loop” (i.e. 10, 100, 500, 763 or more times) An “unknown” number of times (i.e. loop terminates if a tested condition becomes “true” or as long as the tested condition remains “false”), a “while” loop, a “do until” loop, a “do while” loop. This Lab exercise demonstrates the use of the “For Loop”, a standard loop in all programming languages. C++ standard For Loop format looks like: For (n = 1; n <= 100; n++) { Loop line 1 code; Loop line 2 code; Loop line 3 code; Loop line N code; } The loop code needs: A “loop counter variable” (n in the above example) to keep track of how many iterations this loop has run A starting value (i.e. 1 in the above example) A stop test (i.e. run as…arrow_forwardTrue or False? 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.arrow_forward
