Chapter 8, Problem 10RQ

7. Long-Distance CallsA long-distance provider charges the following rates for telephone calls: Rate Category    Rate per MinuteDaytime (6:00 a.m. through 5:59 p.m.)    $0.07Evening (6:00 p.m. through 11:59 p.m.)    $0.12Off-Peak (midnight through 5:59 a.m.)    $0.05Write a GUI application that allows the user to select a rate category (from a set of radio buttons), and enter the number of minutes of the call into an Entry widget. An info dialog box should display the charge for the call.

Name and Address The Name and Address Problem Write a GUI program that displays your name and address when a button is clicked. The program’s window should appear as the sketch on the left side of Figure 13-61 when it runs. When the user clicks the Show Info button, the program should display your name and address, as shown in the sketch on the right of the figure.

Exercise 1 Function and Structure [30 pts] Please debug the following program and answer the following questions. There is a cycle in a linked list if some node in the list can be reached again by continuously following the next pointer. #include typedef struct node { int value; struct node *next; } node; int 11_has_cycle (node *first) if (first == node *head = { NULL) return 0; first; while (head->next != NULL) { } if (head first) { return 1; } head = head->next; return 0; void test ll_has_cycle () { int i; node nodes [6]; for (i = 0; i < 6; i++) { nodes [i] .next = NULL; nodes [i].value = i; } nodes [0] .next = &nodes [1]; nodes [1] .next = &nodes [2]; nodes [2] .next = &nodes [3]; nodes [3] .next nodes [4] .next &nodes [4]; NULL; nodes [5] .next = &nodes [0]; printf("1. Checking first list for cycles. \n Function 11_has_cycle says it has s cycle\n\n", 11_has_cycle (&nodes [0])?"a":"no"); printf("2. Checking length-zero list for cycles. \n Function 11_has_cycle says it has %s…

Question 1 - Array Iterators Like the JS on A2, there is no visual component to this question. The HTML really just needs to load the JavaScript, everything else will output to the console. The JS file should the completion of the task, and all necessary testing, so that just loading the file will complete the task with enough different inputs to ensure it works. Even Numbers [3 marks] Create a function that determines if a provided number is even. Define an array of numbers, then on the array use the appropriate array iterator to determine if the array contains only even numbers using the function you defined. Output the results, and test with several arrays. Long Names [3 marks] Define an array of names. Use an iterator to retrieve a new array containing only the names longer then 12 characters. Your iterator should be passed an anonymous arrow function. Test with several different arrays First Names [3 marks] Define an array called fullNames that contains 7 javascript objects of…

this module is java 731 . make sure my answers are 1005 correct and the layout and structure is perfect and also include all comments etc. thank you i have attached question 1 (40 marks) and question 2 (30 marks )  this is question 3: Question3:                                                                                                                                    (30 MARKS) Passenger Rail Agency for South Africa Train Scheduling System Problem Statement Design and implement a train scheduling system for Prasa railway network. The system should handle the following functionalities: 1. Scheduling trains: Allow the addition of train schedules, ensuring that no two trains use the same platform at the same time at any station. 2. Dynamic updates: Enable adding new train schedules and canceling existing ones. 3. Real-time simulation: Use multithreading to simulate the operation of trains (e.g., arriving, departing). 4. Data management: Use ArrayList to manage train schedules and…
