ft_printf

This project is part of the 42 Prague curriculum.
The goal of ft_printf is to reimplement the standard C printf function.
It is a key project for learning about variadic functions, formatted output, and modular design in C.

📦 Installation & Compilation

1. Clone the repository:
   

git clone git@github.com:ylam21/ft_printf.git ft_printf

cd ft_printf

2. Compile the library:

make

This will produce the libftprintf.a static library.

🚀 Usage

1. Include the header in your source file:

#include "ft_printf.h"

2. Compile your program with the library:

gcc -Ift_printf your_program.c -Llibft -lft -o a.out

-Ift_printf tells the compiler where to find ft_printf.h

-Llibft tells the linker where to find libftprintf.a

-lft links the library

🧹 Makefile Rules

make – Compile the library

make clean – Remove object files (.o)

make fclean – Remove object files and the compiled library (libft.a)

make re – Recompile everything (equivalent to fclean + make)

🧪 Tests

A collection of tests is included in the tests/ folder.

Build the tests

make tests

This compiles all test programs into the tests_bin/ directory.

Run all tests

make run_tests

Each test binary will execute, printing results to the console.

Clean test binaries

make clean_tests

📝 Notes

The project is built on top of your libft library.

Functions follow the 42 norminette coding standard.

ft_printf is often reused in future projects (e.g., cub3d, minishell).
