Review The Example In Appendix E And The Additional Examples On Pp 80

Review the example in Appendix E and the additional examples on pages 80 and 83 of Prelude to Programming. Then, complete Programming Problem 2 on page 109 of Chapter 2 of Prelude to Programming.

The assignment involves developing several small programs based on the provided examples, including inputting and calculating commissions, unit prices, employee pay, bowling scores, and car loan payments. Each program requires specific variables, formulas, and input prompts to produce accurate outputs as demonstrated in the examples. Adhere to the formulas and variable types detailed in the prompts, and ensure proper conversions such as percentages to decimals for interest rates and commission rates.

Sample Paper For Above instruction

The following paper addresses the assignment to review examples found in Prelude to Programming and then develop small programs for different scenarios, demonstrating understanding and application of input, calculations, and output formatting.

Introduction

Programming exercises often build upon foundational examples that showcase input handling, variable utilization, arithmetic computations, and output presentation. In Prelude to Programming, Appendix E and pages 80 and 83 provide illustrative examples that serve as templates for developing various small-scale programs. These examples highlight essential programming concepts and serve as guides for implementing real-world calculations efficiently. The task requires analyzing these examples and creating new programs as specified, each designed to solve particular problems through user input and mathematical formulas.

Review of Appendix E and Additional Examples

Appendix E in Prelude to Programming demonstrates basic input-output operations, variable initialization, and arithmetic calculations. For instance, it might showcase how to input sales figures and compute commissions by multiplying sales amounts by a commission rate that's converted from a percentage to a decimal. Similarly, pages 80 and 83 add examples related to price per ounce calculations and total costs, emphasizing the importance of unit conversions and precise formula application.

These examples serve as effective templates because they clearly outline the steps: prompting user input, converting data types or units where necessary, performing calculations with well-defined formulas, and displaying the results with appropriate formatting. They also illustrate common programming practices such as handling string and float variables, performing arithmetic operations, and using comments to clarify code sections.

By understanding these examples, one learns to construct programs that are both functional and user-friendly, with correct calculations, clear prompts, and easily interpretable outputs. Replicating this structure ensures consistency and correctness across the programs to be developed for the assignment.

Development of the Programs

The assignment involves creating five distinct programs, each with specific inputs, calculations, and outputs:

1. Calculating a saleswoman’s commission: Inputs include sales amount and commission rate; the program converts the commission rate from a percentage to a decimal before computing the commission earned.
2. Unit price calculation for supermarket items: Inputs include item name, weight in pounds and ounces, and the price per pound; outputs are the unit price per ounce and total cost for the purchase.
3. Employee gross and net pay computation: Inputs involve employee ID, hourly wage, regular hours, and overtime hours; outputs are gross pay and net pay after deductions for taxes and parking.
4. Bowling score averages: Inputs are scores for three games for each player; outputs include individual averages and team total score.
5. Car loan monthly payment calculation: Inputs are loan amount, annual interest rate, and number of payments; outputs the monthly payment computed using the appropriate formula.

Each of these programs emphasizes critical programming skills: input handling, variable assignment, arithmetic calculations with correct formulas, and formatted output. Special attention should be given to unit conversions (e.g., pounds and ounces to total ounces), percentage-to-decimal conversions (interest rates and commission rates), and exponentiation in loan calculations.

Conclusion

Through careful review of the provided examples and understanding of the formulas and logic demonstrated therein, one can replicate and adapt these structures to new problems efficiently. This exercise enhances programming skills by translating real-life scenarios into executable code—an essential step toward mastering programming fundamentals and developing functional applications.

Implementing these programs not only demonstrates comprehension of the concepts but also reinforces the importance of clear, logical structuring in coding practice. By following the examples and applying correct formulas and data handling, learners can produce accurate and user-friendly programs that solve practical problems effectively.
