### Question: Understanding While Loops**Which of the following statements is true?** 1. **The boolean test that makes up the loop test is found in the body of the loop.**2. **The keyword while indicates the type of loop (pre-test).**3. **The loop body is indented at the same level as the keyword while.**4. **The boolean expression is followed immediately by the keyword end.**---**Explanation:**When learning about loops, particularly the `while` loop, it's important to understand the structure and elements that constitute the loop. - **Statement 1:** This is *incorrect* because the boolean test in a while loop is not found in the body of the loop; it is found in the loop declaration. - **Statement 2:** This is *true*. The keyword `while` indeed indicates a pre-test loop, meaning it evaluates the boolean expression before entering the loop body.- **Statement 3:** This is *incorrect*. Typically, the loop body is indented to signify that it belongs to the loop block rather than being at the same level as the `while` loop declaration.- **Statement 4:** This is *incorrect*. In most programming languages, the boolean expression in a `while` loop is followed by the loop body, not by a terminal keyword like `end`.Understanding these key components helps better manage and utilize `while` loops in programming.

The key word while indicates the type of loop pre test. The while keyword contains a condition or…

Problem: Feed Nibble Monster As Long As It Is Happy Write a program in which the Nibble Monster happily keeps asking for nibbles until the user gives it something that is not a nibble. At that point the monster becomes unhappy and the loop ends. Use do-while loop. HINT: You can control the loop with a boolean variable which indicates the state of Monster's feelings: it is true initially but becomes false when the Monster receives a non-nibble.

Overview This program will prompt a user for a start and a limit, it will then while-loop through, doubling the iterator each pass, until the limit is reached. 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…
Looping Construct with Floating Point Numbers Write a program that utilizes a while-loop to read a set of five floating-point values from user input. Include code to prevent an endless loop. Ask the user to enter the values, then print the following data: Total Average Maximum Minimum Interest on total at 20% Answer:
pow(3,4)=? Select one: O a. 81 O b. 12 c. 64 O d. 7
The 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)
All 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…
Q5: (Display patterns using loops) Use nested loops that display the following patterns. Your program should prompt the user to input A, B, or C, and display the corresponding pattern. The program ends with the input -1. (2 marks) Pattern A Pattern B Pattern C * ******* ** *** ** k** *** **** **** * **** *** **** k* * ** ** *** ******* *** ***
Direction: Read each sentence/ situation carefully and select the BEST answer among the choices. 1. It is a Boolean expression that tells when the loop will exit. 2. The sequence that makes up the loop body may either be a block of Turbo C statements or a single Turbo C statement. 3. In Turbo C it is a reserved word. 4. Its values determine the number of times the loop iterates. 5. It is the second type of open-ended loop. Condition For Loop Statement For Do while Loop
Write the code to display the following pattern using two pretest loops along with the letter X. Use the Do...Loop statement for the outer loop. Use the For...Next statement for the nested loop. Display the pattern in the lblPattern control.XXXXXXXXXXXX
computer programming Loop is used to repeat a sequence of actions or statements many times. Simplydescribe the differences between for-loop and while-loop.
Python Coding-While Loops (In PyCharm Community edition) Create a while loop that SUMS up ALL the numbers given from an initial number and an ending number. Example would be : Input1 : What is the first number? 0 Input2 : What is the last number? 3 DO NOT SHOW but these are the computations inside the code : 0 + 1 + 2 + 3 = 6 This is the Output : The sum of all the number from 0 to 3, is 6 In the code you are going to use a total variable and add each additional time it runs through the loop to that total. REMEMBER the assignment from the first unit of programming where we used this formula : BUT you are going to create your own method using a while loop to emulate what formula accomplishes WITHOUT using this formula. The user will put in the first number and the last to be SUMMED - you will use the while loop to calculate all of the additions leading to the final number.
Indicate whether the statement is true or false.
