Create a Complete C# Windows Application and Design Document
The objective of this individual project is to create a complete C# Windows application and the associated design document based on the specified requirements. The application must calculate and display a letter grade for each student, utilizing arrays to store data, and include various methods to manipulate and process the data. The project requires the development of a comprehensive problem analysis chart, flowchart, pseudocode, and reflection on challenges encountered during development. The solution should demonstrate an understanding of programming concepts such as algorithm design, data structures, object-oriented programming, and event-driven programming, while also providing clear documentation and analysis tools.

Introduction
The development of a Windows application to process and analyze student grades serves as a practical exercise in applying core programming principles, including event-driven programming, data structures, and object-oriented design. This project aims to create an intuitive interface that efficiently inputs, processes, and outputs student grade data, encapsulating the entire process within a well-structured codebase complemented by thorough documentation. The application not only performs the core task of calculating and assigning letter grades but also provides tools for data management and program flow visualization, fostering a comprehensive understanding of software development processes.
Problem Analysis and Requirements
The primary problem involves accepting student information and numerical grades, calculating their corresponding letter grades based on predefined grading standards, and displaying these results. The system must facilitate multiple data entries, display stored data logically, and allow for data management through clearing and resetting functions.
Given Information:
- Student data such as names and numerical grades.
- Grading scale for converting numerical grades into letter grades.
- Requirements for input validation and data storage.
Required Results:
- Input student information via textboxes.
- Populate an array with student data.
- Display results in a ListBox.
- Calculate averages and assign letter grades.
- Provide options to clear and reset data fields.
- Show processing flow through diagrams.
Processing Needed:
- Read data from textboxes.
- Store data in arrays (single or multidimensional).
- Convert numerical grades to letter grades based on the grading scale.
- Populate the ListBox from the array data.
- Calculate and display the class average.
- Reset form controls to default state.
Solution Alternatives:
- Use multidimensional arrays or lists for dynamic data handling.
- Implement individual methods for specific tasks (fill arrays, populate list box, clear data, compute averages).
- Use event handlers for button clicks to trigger respective functions.
- Incorporate validation routines to ensure data integrity.
Design and Implementation
A. Arrays:
The program utilizes a multidimensional array or a list of objects to efficiently store student information, including names and grades. For example:
```csharp
string[,] students = new string[50, 2]; // 50 students, 2 columns (name, grade)
```
or, preferably, a list of student objects:
```csharp
public class Student
{
public string Name { get; set; }
public int Grade { get; set; }
public string LetterGrade { get; set; }
}
List
```
B. Core Methods:
- FillArrayFromTextboxes(): Reads user input, validates, and adds data to the array/list.
- PopulateListBox(): Displays stored data in the ListBox.
- ClearForm(): Clears all input fields.
- ResetForm(): Resets the form controls to initial states.
- CalculateAverage(): Computes the class average of grades.
- AssignLetterGrade(): Converts numerical grade to the appropriate letter grade.
C. Flowchart:
The flowchart begins with program start, proceeds to user input, validates data, stores information, calculates grades, updates display, and waits for further user interactions such as clear or reset commands, looping as necessary until exit.
D. Pseudocode:
```
Start
Initialize data structures
Repeat
Prompt user for student name and grade
Validate inputs
If valid, store in array/list
Else, display error
Display current data in list box
Ask user if they want to add another student
Until user chooses to stop
Calculate class average
For each student in list
Convert numerical grade to letter grade
Update display
Provide options for Clear and Reset
End
```
Challenges and Resolutions
During development, several challenges arose, including handling input validation errors, managing array indexing, and ensuring correct event handler execution. For instance, initial attempts at using fixed-size arrays limited scalability, leading to the decision to use List
Conclusion
This project encapsulates fundamental programming principles, emphasizing structured problem-solving, data management, and event-driven design in C#. By creating a user-friendly interface integrated with robust backend processes, the application demonstrates practical application of algorithms, object-oriented programming, and software analysis tools. The inclusion of design documentation such as flowcharts and pseudocode enhances understanding and maintenance, reflecting best practices in software development.
