Printf Evaluation Process

Printf Evaluation Process

This folder contains a small testing environment to help you verify the behavior of your ft_printf implementation for the 42 Common Core project.

📁 Folder Structure

• mains/ — Test files
• Makefile — Compiles all tests
• README.md — This documentation file

🚀 How to Use

1. Place your ft_printf source files inside a folder named src/.
2. Run:

make

3. Execute the generated test programs:

./test_basic
./test_numbers
./test_hex_pointer
./test_mixed

Each test displays:

• Output printed by ft_printf
• Output printed by the real printf
• Return values for both (so you can compare correctness)

🎯 Purpose of This Repo

This testing setup helps you easily validate:

• Output correctness
• Matching return values
• Proper handling of edge cases:
  • NULL strings
  • Negative numbers
  • Unsigned values
  • Hexadecimal formatting
  • Pointer formatting

It is especially useful when preparing for the 42 evaluation.
