Name Formatting
Create an application that lets the user enter a person’s name as a last name, comma, and first name. An example is “Fernandez, Frank”. Redisplay the name as the first name, a space, and the last name. An example is “Frank Fernandez”.
Display an error message if the user forgets to insert a comma in the input name. The output should be correct whether or not the user includes a space after the comma in the input string. Be sure to test the

- Pendant Publishing edits multi-volume manuscripts for many authors. For each volume, they want a label that contains the author’s name, the title of the work, and a volume number in the form Volume 9 of 9. For example, a set of three volumes requires three labels: Volume 1 of 3, Volume 2 of 3, and Volume 3 of 3. Design an application that reads records that contain an author’s name, the title of the work, and the number of volumes. The application must read the records until eof is encountered and produce enough labels for each work. Design a flowchart and psuedocode Pendant Publishing.arrow_forwardDriver’s License Exam The local driver’s license office has asked you to create an application that grades the written portion of the driver’s license exam. The exam has 20 multiple-choice questions. Here are the correct answers: 1. B 2. D 3. A 4. A 5. C 6. A 7. B 8. A 9. C 10. D 11. B 12. C 13. D 14. A 15. D 16. C 17. C 18. B 19. D 20. A Your program should store these correct answers in an array. The program should read the student’s answers for each of the 20 questions from a text file and store the answers in another array. (Create your own text file to test the application.) After the student’s answers have been read from the file, the program should display a message indicating whether the student passed or failed the exam. (A student must correctly answer 15 of the 20 questions to pass the exam.) It should then display the total number of correctly answered questions, the total number of incorrectly answered questions, and a list showing the question numbers of the incorrectly…arrow_forwardFunction for button "Publishing Date": • Name this function by your last name (for example, function yamoutl)).

- Microsoft Visual C# 7th edition. need help, please. Thanks In previous chapters, you created applications for Marshall’s Murals. Now, modify the version of the MarshallsRevenue program created in Chapter 5 so that after mural data entry is complete, the user is prompted for the appropriate number of customer names for both the interior and exterior murals and a code for each that indicates the mural style: L for landscape S for seascape A for abstract C for children’s O for other When a code is invalid, re-prompt the user for a valid code continuously. For example, if Y is input, output Y is not a valid code, and re-prompt the user until a valid code is entered. After data entry is complete, display a count of each type of mural. For example the output should be in the following format with the correct number next to each mural type: The interior murals scheduled are: Landscape 1 Seascape 2 Abstract 1 Children's 3 Other 9 The exterior murals scheduled are: Landscape 4 Seascape 0…arrow_forwardc++ The Seri Kuala Lumpur School auditorium contains 20 rows (numbered 1 through 20) with 30 seats each (numbered 1 through 30). Write an application that allows a user to continuously enter a row and seat request until a sentinel value is entered. If the row or seat number is out of range, issue an error message. Otherwise, determine whether the seat has already been reserved. If so, display an error message. If not, then charge the user $7.50 for a ticket and display a running total of the user’s purchase. When the user enters a sentinel, display the number of seats taken and the number of seats available in the auditorium.arrow_forwardDice Simulator Create an application that simulates rolling a pair of dice. When the user clicks a button, the application should generate two random numbers, each in the range of 1 through 6, to represent the value of the dice. Use PictureBox controls to display the dice. (In the Student Sample Programs, in the Chap05 folder, you will find six images named Die1.bmp, Die2.bmp, Die3.bmp, Die4.bmp, Die5.bmp, and Die6.bmp that you can use in the PictureBoxes.)arrow_forward
- VBA PROBLEM: Create a code where every time that only cell B1 is changed, create a new tab and that this tab is renamed with the value that is entered in B1 and the other cells, that is, B2: B11 have the same values that are entered in the Sheet1. The values of A1: A11 must always remain the same. Like in the examples below (image 1 and 2).arrow_forwardPlease provide answer in C#: Slot Machine Simulation A slot machine is a gambling device into which the user inserts money and then pulls a lever (or presses a button). The slot machine then displays a set of random images. If two or more of the images match, the user wins an amount of money that the slot machine dispenses back to the user. Create an application that simulates a slot machine. Figure 8-23 (on page 539 of your book) shows an example of how the form should look. The application should let the user enter into a TextBox the amount of money he or she is inserting into the machine. When the user clicks the Spin button, the application should display three randomly selected symbols. (Slot machines traditionally display fruit symbols. You will find a set of fruit symbols attached to this dropbox for your use - from the Student Sample Programs provided by the book author.) If none of the randomly displayed images match, the program should inform the user that he or she has won…arrow_forward8.

After the user clicks a Button (with Count as its Text), calculate and display the number of characters in a Label on the form, ignoring blank spaces in the sentence. For example, If the user enters "I like it", display "A total of 8 characters" (the two blank spaces are omitted). Zip the project folder and submit the zipped file.

The application should be designed with checkboxes to select the various services (such as office call, vaccination, grooming, etc). As each service is selected, the charge for the service should display in an associated label. (When the checkmark is removed, the amount should be removed). As each selection is made, the charges should be added into the total (a variable… consider scope), and displayed in a Total Due area on the application (currency format). Align all numeric data appropriately. Consider what should happen when the checkmark is removed. Include at least 8 services that your pet clinic performs. Include a Clear and Exit button. The clear should clear all checkboxes, appropriate labels, and the total variable. Use the standard Microsoft naming conventions for all controls. Include appropriate comments in your code.
