39. If a programmer tested the following code with the values indicated, would the program cor- rectly calculate the average of the test scores? Assume all variables and lists have been appro- priately initialized. FOR EACH score IN testScores { IF score> 0 ( total total } count count 1 } DISPLAY ("The average score on the test was: ", total / count) 80, 85, 50, 0, Test1 [100, 90, 80, 85, 90) Test2 [192, 85, 74, 100, 96, 88] score (A) Yes, the code works as it should for both test cases. (B) No, the code does not average the test scores correctly for either test. (C) No, the code only works for the Testl scores. (D) No, the code only works for the Test2 scores. 40. When should a heuristic algorithm be used? (A) When a problem is unable to process in reasonable time but a "close enough" solu- tion is acceptable (B) When the data is not sorted and cannot be placed in the order needed (C) When a problem is undecidable because not enough information is known (D) When searching is needed but efficiency is a requirement 41. How many times do FOR EACH loops run with lists? (A) Once (B) Until the index for the list is 0 (C) For the LENGTH of the list (D) Until the user types STOP

Transcribed Image Text Develop a C++ code to computer the queries in X Y z format where you are given a list of size m. For computing queries, you have to perform the task to find the number which is occurring one after another in the sub-list [X Y] greater than or similar to z times. If there doesn't exist no number satisfying the given criteria then output “Not possible" other than that output the answer computed to the given queries. Test Case Result 4 1 2133 121

help me solve this in c++ please Write a program that asks the user to enter a list of numbers from 1 to 9 in random order, creates and displays the corresponding 3 by 3 square, and determines whether the resulting square is a Lo Shu Magic Square. Notes Create the square by filling the numbers entered from left to right, top to bottom. Input validation - Do not accept numbers outside the range. Do not accept repeats. Must use two-dimensional arrays in the implementation. Functional decomposition — Program should rely on functions that are consistent with the algorithm.

Write VBA CODE FOR THE FOLLOWING PROBLEM Problem: The Worksheet named Grades contains a place for students to record the grades they have received in their classes. Students put the number of each letter grade received in the B column. (For example, the worksheet currently shows that the student has taken 9 classes and made five As, one B, one C, one D, and one F as grades. You need to write a program that reads the grades from the worksheet and uses a function to calculate the student’s GPA. For this problem you can assume that all classes are worth the same number of credit hours. The function should send back the GPA to the calling procedure. The procedure will then put up a message box that gives the student their GPA and a message about their GPA, all in one message box. The message should be “You qualify for an internship” if the student has a GPA of at least 3.0. It should be “You’re in the danger zone” if the GPA is between 2.0 and 3.0. And it should be “You are on…
Create a c++ shopping cart program using: linked list- - this will be used as the customer's cart. This is where the items that the customer will buy are placed before checking them out. Array - to store your store products. Pointers - since you will be using linked lists, it is imperative that you also will be using pointers. Functions - Make sure that your program will have user-defined functions (e.g.: function for adding nodes, function for displaying the cart, etc.) The menu options would be cout
ASSIGNMENT: Write a program to use the capability of Recursion to calculate factorials. For example, 5 factorial is normally written as 5! 5! = 5*4*3*2*1 5! = 120 Use recursive function calling to multiply. 5*4*3*2*1 And then print the result. 120 Your output should resemble the image below. >sh -c jav d. -type f > java -cla 5 4 2 5! = 120 } Note: 5! is use in this example but your program should calculate the factorial for any number entered.
