C Programming Problem Solver

Python utility that reads programming questions, generates C solutions via G4F, compiles/runs them locally, and exports a PDF report.

Features

• AI-based C code generation using g4f
• Local compilation/execution via gcc
• Automatic input simulation for common scanf formats
• Parallel question processing
• PDF export with question, code, and runtime output
• Fallback handling for model/compile/runtime errors

Requirements

• Python 3.6+
• GCC available on PATH
• Python packages:
  • fpdf
  • g4f

Installation

1. Clone this repository.
2. Install dependencies:

pip install fpdf g4f

3. Ensure gcc is installed and callable from terminal.

Usage

1. Create questions.txt with one question per line.
2. Run:

python3 main.py

3. Output PDF is created as code_solutions.pdf.

Configuration

Edit values in config.py:

• QUESTIONS_FILE (default: questions.txt)
• FINAL_PDF (default: code_solutions.pdf)
• MAX_WORKERS (default: 4)

Project Structure

• main.py: Entry point and orchestration
• config.py: Central configuration
• question_io.py: Read questions from file
• codegen.py: G4F prompt/call and code cleanup
• runner.py: GCC compile + execution simulation
• processor.py: Per-question processing pipeline
• pdf_builder.py: PDF layout and rendering
• text_utils.py: Text cleanup and formatting helpers

Example Input

Write a program to find the factorial of a number.
Create a program that checks if a number is prime.

Notes

• Generated prompts include student identification lines in the produced C code.
• Compilation timeout is 10 seconds; execution timeout is 5 seconds.
• Text is normalized for PDF Latin-1 compatibility.
