C Programming Problem Solver

A Python utility that automatically generates C code solutions for programming problems, compiles them, and creates a comprehensive PDF report.

Overview

This tool takes a list of programming problems from a text file, uses AI to generate C code solutions, compiles and runs the code locally, and produces a professional PDF document containing all problems, solutions, and execution outputs.

Features

• AI-Powered Code Generation: Utilizes the G4F client API to generate C code solutions
• Local Compilation & Testing: Automatically compiles and runs the generated code
• Input Simulation: Intelligently detects and simulates user input requirements
• Parallel Processing: Processes multiple problems simultaneously for efficiency
• Comprehensive PDF Reports: Creates well-formatted PDF documentation with all solutions
• Error Handling: Gracefully handles compilation errors and execution timeouts

Requirements

• Python 3.6+
• GCC compiler (accessible via PATH)
• Required Python packages:
  • fpdf
  • g4f

Installation

1. Clone this repository or download the script
2. Install required Python packages:

pip install fpdf g4f

3. Ensure GCC is installed and accessible from your command line

Usage

1. Create a questions.txt file with one programming problem per line
2. Run the script:

   python3 main.py
   

3. A PDF file named code_solutions.pdf will be generated with all solutions

Configuration

You can adjust the following parameters at the top of the script:

• QUESTIONS_FILE: Path to the file containing programming problems (default: 'questions.txt')
• OUTPUT_FOLDER: Directory for storing temporary outputs (default: 'output')
• FINAL_PDF: Name of the output PDF file (default: 'code_solutions.pdf')
• MAX_WORKERS: Maximum number of parallel processes (default: 4)

How It Works

1. The script reads programming problems from the questions.txt file
2. For each problem, it:

• Sends the problem to an AI model via G4F API to generate C code
• Compiles the generated code using GCC
• Detects input requirements from scanf statements
• Generates appropriate random inputs when needed
• Captures the execution output

3. All problems, code solutions, and outputs are compiled into a PDF document
4. The PDF includes proper formatting with:

• Problem statements
• C code solutions with syntax formatting
• Execution outputs
• Input/output simulation details

Example

Input file (questions.txt):

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

Output: A PDF file containing each problem, its C code solution, and execution output.

Customization

• Student information can be modified in the get_c_code_from_g4f function
• PDF formatting can be adjusted in the ProblemPDF class
• Input generation can be customized in the generate_random_input function

Troubleshooting

• If compilation fails, check that GCC is properly installed
• If the AI fails to generate code, try adjusting the prompt in get_c_code_from_g4f
• For timeout errors, increase the timeout values in the run_code_locally function

Notes

• The program automatically adds student identification information (name, roll number, section)
• Unicode characters in code or output are cleaned and converted to ASCII equivalents
• The tool handles timeouts for both compilation (10 seconds) and execution (5 seconds)
