(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…

Visual BAsicsarrow_forwardIn this exercise, you modify the Grade Calculator application from this chapter’s Apply lesson. Use Windows to make a copy of the Grade Solution folder. Rename the copy Grade Solution-Intermediate. Open the Grade Solution.sln file contained in the Grade Solution-Intermediate folder. Open the CourseGrade.vb file. The DetermineGrade method should accept an integer that represents the total number of points that can be earned in the course. (Currently, the total number of points is 200: 100 points per test.) For an A grade, the student must earn at least 90% of the total points. For a B, C, and D grade, the student must earn at least 80%, 70%, and 60%, respectively. If the student earns less than 60% of the total points, the grade is F. Make the appropriate modifications to the DetermineGrade method and then save the solution. Unlock the controls on the form. Add a label control and a text box to the form. Change the label control’s Text property to “&Maximum points:” (without the quotation marks). Change the text box’s name to txtMax. Lock the controls and then reset the tab order. Open the form’s Code Editor window. The txtMax control should accept only numbers and the Backspace key. Code the appropriate procedure. The grade should be cleared when the user makes a change to the contents of the txtMax control. Code the appropriate procedure. Modify the frmMain_Load procedure so that each list box displays numbers from 0 through 200. Locate the btnDisplay_Click procedure. If the txtMax control does not contain a value, display an appropriate message. The maximum number allowed in the txtMax control should be 400; if the control contains a number that is more than 400, display an appropriate message. The statement that calculates the grade should pass the maximum number of points to the studentGrade object’s DetermineGrade method. Make the necessary modifications to the procedure. Save the solution and then start and test the application.arrow_forward
- Create an application named SalesTransactionDemo that declares several SalesTransaction objects and displays their values and their sum. The SalesTransaction class contains fields for a salesperson name, sales amount, and commission and a readonly field that stores the commission rate. Include three constructors for the class. One constructor accepts values for the name, sales amount, and rate, and when the sales value is set, the constructor computes the commission as sales value times commission rate. The second constructor accepts a name and sales amount, but sets the commission rate to 0. The third constructor accepts a name and sets all the other fields to 0. An overloaded + operator adds the sales values for two SalesTransaction objects.arrow_forwardSpecifications: Lions, Tigers, and Bears Pet Clinic needs an application that displays basic services. 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.
