This repository began as my solutions to the exercises in Introduction to Programming with C++ (3rd Edition) International Edition by Y. Daniel Liang. It now documents the transition from solving those book-based problems to crafting high-quality prompts for Codex, OpenAI's code generation model.

Starting from Chapter 12, each solution is designed as a Codex prompt followed by AI-generated C++ code. Earlier chapters contain hand-written solutions created while progressing through the book, sticking to the rule that no syntax is used before it appears in the text. The original problem statements are not included here due to copyright restrictions.

I am learning this as a hobby, so updates are not regular.

1. Each chapter directory from Chapter 12 onward contains a prompt.md describing the problem.
2. Provide the prompt to Codex and let it generate an initial C++ solution.
3. Review, run, and refine the generated code.
4. Commit both the prompt and the final code so readers can see the prompt–response pair.

If you'd like to contribute:

• Write prompts in Markdown with a clear title, description, constraints, and sample I/O.
• Place prompts and generated solutions in the appropriate chapter directory.
• Keep prompts and solutions in separate blocks and note any manual edits made to the AI-generated code.
