Question

GUI Program Development Activity (C#)

You are required to demonstrate the four-stage process of program development: analysis, design, implementation and testing and as such your service is retained as a business analysis to design a simple student grade program. The program should achieve the following objectives:

1. Design an interface and implement the following.

2. Records the students name.

3. Accepts 7 test scores for the student.

4. Calculates the sum of the scores.

5. Calculates the average of the scores calculated.

6. Displays the test scores.

7. Displays the average of the test scores.

Your deliverables are: A. Submit a screen capture and code
