1) Create a WPF application that would do the following tasks:
a) Create a new class for the Introduction to programming course and call that class IntroToProg. This class must have methods and fields. One of the fields must be an array. Below are some suggestions:
i. Two public fields. One for the total score and the other is an array that would hold the scores of the four assignments.
ii. A method that would set the scores of the four assignments that the user enters equal to the assignments in the array.
iii. A method that would get the final score.
b) Ask the user for the scores of the four assignments. In this project, assume that the introduction to programming course has only four assignments and that the final grade for this course is based on these four assignments.
i. When the user clicks on the Display Assignments button, you want to do the following
1. Set the assignments scores in your IntroToProg class equal to what the user enters.
2. Using a loop, display the scores of the four IntroToProg class assignments in a list box when the user clicks on the Display Assignments button.
ii. Clear the scores in the list box when the user clicks on the Clear List button.
iii. Display the final grade for this IntroToProg class when the user clicks on the Calculate button as follows:
1. The grade is A if the total score is greater or equal to 390.
2. The grade is B if the total score is less than 390 and greater or equal to 380.
3. The grade is C if the total score is less than 380 and greater or equal to 350.
4. The grade is F otherwise.
a) In the screen shots above I used a group box control to include the assignments in one place (Inside that group box.) You can add the labels and textboxes controls first to the form and then add the group box control next. Make sure to set the group box order property to
