This Project Provides You With An Opportunity To Write An Application
This project provides you with an opportunity to write an application (i.e., computer program) by using a problem specification (output, input, and algorithm) and then creating the application in Visual Basic. Your application should use at least one of the following structures: sequence, selection, and/or repetition.
1. Select ONE of the following tasks as the basis for completing this project: • changing a television channel by using a remote control • using a sponge to wash a car • walking up a set of stairs • a game of your choosing • net income calculator • measurement calculator • discount calculator • sales calculator • labor calculator • totals calculator • membership calculator • inventory calculator
2. Select at least three of the concepts from Chapters 1-11 and apply this to your Windows application, which solves a problem. These are concepts you learned in this course and are listed below: • arithmetic operator • If… Then… Else statement • nested selection structure • multiple-alternative selection structure • testing method • looping condition

Introduction
The purpose of this project is to develop a Windows application in Visual Basic that addresses a real-world problem through a user-friendly interface while demonstrating proficiency in core programming concepts such as sequences, selection, and repetition. Selecting an appropriate task from the provided list enables the practical application of programming structures learned in this course. This paper outlines the problem,
the proposed algorithm, and the underlying concepts that guide the development process.
Chosen Task and Problem Description
I have selected the "net income calculator" as the task for my project. The purpose of this application is to help individuals determine their net income by considering gross income, taxes, deductions, and other possible expenses. The application aims to provide a straightforward interface where users input their gross income and deductions, and the system computes their net income. This calculator can be beneficial for personal finance management, budgeting, or preliminary financial planning.
Algorithm Development and Pseudocode
Developing a clear algorithm is essential for guiding the application’s functionality. The algorithm encompasses user inputs, calculations, and output display, structured with decision-making and looping constructs as needed.
Pseudocode
BEGIN
DISPLAY "Net Income Calculator"
PROMPT user to enter gross income
INPUT grossIncome
PROMPT user to enter total deductions
INPUT totalDeductions
SET taxableIncome = grossIncome - totalDeductions
IF taxableIncome <= 0 THEN
netIncome = 0
ELSE
COMPUTE taxes based on taxableIncome using progressive tax rates
taxes = CalculateTaxes(taxableIncome)
netIncome = taxableIncome - taxes
DISPLAY "Your net income is: " + netIncome
Application of Programming Concepts
In developing the net income calculator, several core programming concepts are applied:
Arithmetic operator:
Used for calculations such as gross-income minus deductions and tax computations.
If… Then… Else statement:
Implements decision-making for different tax brackets and income situations, ensuring accurate tax calculations based on taxable income.
Looping condition:
While not central in this simplified example, it can be incorporated if the application is extended to process multiple inputs or perform iterative calculations.
User Interface Design
The application features a clean, user-friendly interface with labeled text boxes for inputting gross income and deductions. A button to calculate net income triggers the processing, and a label or message box displays the result. The interface allows for easy navigation and enhances user experience, aligning with the functional requirements derived from the pseudocode.
Conclusion
This project exemplifies how programming concepts such as sequences, selection, and repetition can be integrated into a practical Windows application in Visual Basic. The net income calculator demonstrates core programming logic, decision-making, and user interface design, providing valuable skills applicable in broader software development contexts.
