Use Visual Basic .Net 2012 To Program, Debug, And Test

Use Visual Basic .Net 2012 to program, debug, and test the following programming project

Use Visual Basic .Net 2012 to program, debug, and test the following programming project. Create a GPA calculator. Ask the user to input a list of classes and the number of tests per class. Once the user has entered this initial information, allow the list to be saved when the user exits the program. When the program starts, any existing data should be loaded automatically. After the user has entered the list of classes and number of tests for each class, the user can then enter grades for each test. Create a button that allows the user to request a GPA calculation at any time. (GPA = average for each class averaged for the total number of classes in a semester.) All programs should have basic menu options that allow the user to exit the program and perform tasks you deem necessary for the program to function correctly. After creating the program, be sure to debug and test your code. When you are finished, zip your project file and submit to your instructor for grading. Submit a screenshot of the executed program and the code of the program. Write a small word file separate from the zip file discussing the Program Design processes and steps while working on the assignment.

Creating a GPA Calculator Using Visual Basic .NET 2012

The task of developing a GPA calculator in Visual Basic .NET 2012 involves multiple stages, including planning, designing, coding, debugging, and testing the application. This project emphasizes creating a user-friendly interface that allows students to input their classes, tests, and grades, while also ensuring seamless data persistence and retrieval. Throughout this process, principles of good software design, data handling, and user experience considerations are paramount.

Program Design and Planning

The initial planning comprehended defining the core functionalities: input of classes and number of tests, entering grades, calculating GPA, data persistence, and providing menu options such as exit and data management. The program's architecture had to accommodate dynamic data structures, predominantly using lists or arrays to allow the user to enter an arbitrary number of classes and tests.

A key aspect was creating an intuitive user interface. This typically involves using controls like TextBoxes for data entry, Buttons for operations such as calculating GPA, Save, and Load, along with ListBoxes or DataGridViews to display class lists, test grades, and results. MenuStrip controls might provide menu options for actions like saving data, loading previous data, and exiting.

Core Components and Data Structures

The fundamental data structures involve maintaining lists or dictionaries to store class names, the number of tests, and grades. For instance, a List of Class objects where each Class object contains the class name, number of tests, and a collection of individual grades. This enables flexible data handling and easy updates.

Implementation Strategy

Implementation is conducted in stages:

1. Creating the user interface with the necessary controls, including input fields, buttons, and display areas.
2. Implementing data entry: dynamically generating input fields based on user entries for classes and tests.
3. Saving and loading data: serializing objects or data structures to a file when the program exits and deserializing upon startup, ensuring data persists across sessions.
4. Calculating GPA: iterating through each class and its test grades to compute averages, then computing the overall GPA.
5. Adding menu options and event handlers for program control like exit, save, load, and GPA calculation requests.

Debugging and Testing

Thorough debugging included verifying data input validation, ensuring correct calculations, and checking file I/O operations. Testing involved entering various datasets, including edge cases like zero classes or zero tests, and confirming that GPA calculations and data persistence work correctly. Debugging tools integrated in Visual Basic, such as breakpoints and watch windows, supported the process.

Conclusion

Developing this GPA calculator encapsulates key software engineering principles—user input handling, dynamic UI updates, data serialization, and iterative testing. The project enhances understanding of event-driven programming, file handling, and basic algorithms necessary for calculating averages and GPAs. Proper documentation and debugging ensure the application's robustness, making it a functional academic tool.
