Implement The Following Algorithm In C# Using WFA GUI

Implement the following algorithm in C# using WFA GUI. Submit source and run window as a zip file in assignment box. Start, declare variables, print “Enter student first name”, input studFirstName, print “Enter student last name”, input studLastName, print “Enter score for exam 1”, input studExam1, print “Enter score for exam 2”, input studExam2, print “Enter score for exam 3”, input studExam3, compute studScore = studExam1 + studExam2 + studExam3, compute studAvg = studScore / 3, print “Student’s Final Grade”, determine grade based on studAvg, and display grade.

Create a gradStudent class which inherits from the Student class created earlier. The gradStudent class should include the data members: string bsDegreeName, float bsGPA, string ProgName. Create two constructors, one of which is the default constructor. Test the gradStudent class by creating a graduate student object.

Introduction

The implementation of applications with graphical user interfaces (GUI) has become a fundamental aspect of modern software development, especially when aiming to improve user experience and interaction. C# Windows Forms Application (WFA) provides a robust platform for constructing user-friendly interfaces. This paper describes the implementation of a student grading system, incorporating object-oriented programming concepts by creating a specialized class for graduate students. The project demonstrates data collection, processing, and display through a GUI, and extends functionality via class inheritance.

Design and Implementation of Student Grading System

The core of the application involves capturing students' personal information and assessment scores, calculating their average, and assigning a corresponding grade. The GUI-based approach facilitates intuitive data entry and provides immediate feedback. In C#, Windows Forms enables rapid development and deployment of such applications with minimal complexity.

The program begins with designing a form that contains input fields for the student's first name, last name, and scores for three exams. These inputs are captured through text boxes, and upon clicking a 'Calculate' button, the program processes the data to compute total scores and the average. Based on average scores, the program assigns a letter grade following standard grading criteria:

- 90–100: A

- 80–89: B

- 70–79: C

- 60–69: D

- Below 60: F

The associated logic uses conditional statements to determine the grade in real-time, displaying it on the interface. This immediate visual feedback enhances user interaction.

Object-Oriented Programming: Creating a Student and Graduate Student Class

Beyond the core functionality, the project extends to demonstrate class inheritance in C#. Initially, a base 'Student' class is created with basic attributes such as first name, last name, and scores. The 'gradStudent' class inherits from 'Student', adding specific data members: bsDegreeName, bsGPA, and ProgName. This models real-world scenarios where graduate students have additional academic information beyond undergraduate students.

Constructors in the 'gradStudent' class are implemented to initialize objects with default and parameterized values, demonstrating object-oriented principles such as encapsulation and constructor overloading. Testing involves instantiating a 'gradStudent' object and displaying its properties, which confirms the correctness of inheritance and class design.

Development and Testing

The application is developed using Visual Studio with Windows Forms Designer, creating a seamless interface for input and output. Event handlers are used to trigger calculations when the user interacts with the GUI. Testing involves inputting sample data and verifying that the correct grade calculation and student data display occur.

The extension to include the 'gradStudent' class provides a comprehensive demonstration of inheritance. It shows how graduate-specific information can be integrated into the broader student data management system.

Conclusion

This project exemplifies effective use of C# Windows Forms for creating interactive academic applications. It combines fundamental programming constructs, GUI design, and object-oriented principles to develop a functional student grading system and a derived graduate student class. Such implementations are valuable for educational management systems and provide a foundation for further feature enhancements, such as database integration, multi-student processing, and advanced reporting.
