This session explains the difference between a program that merely works and a program that is well written. A program may produce the correct answer but still be poor quality if it is difficult to read, maintain, test, or extend.

Problem Statement

Write a program that is correct but not of good quality. Justify your answer. Make necessary assumptions.

Expected Deliverable

Provide a working program and explain why it is poor quality even though it gives correct output.

Example Quality Problems

• Unclear variable names.
• Duplicated code.
• No input validation.
• No comments for complex logic.
• Hard-coded values.
• Poor formatting.
• No separation into functions.

Evaluation Notes

A program can be correct for a sample input but still have poor maintainability, readability, testability, and extensibility.

Submission Checklist

• Include the program.
• Show sample output proving it works.
• List quality issues.
• Suggest improvements.
