# ft_printf

## Summary

The goal of this project is to retro-engineer the `printf()` function in C, providing a deep understanding of variadic functions in C.

## Git Repository Contents

- `Makefile`: Script for compiling source files with necessary flags.

- `*.h` : Header files containing function prototypes.

- `*.c` : Source files implementing the `ft_printf()` function and any additional features.

## Acquired Skills

### C Programming

- Implementation of a complex function (`ft_printf()`) in C.

- Adherence to the `School 42` C coding standard.

- Handling of variadic functions.

- Unit testing.

### Memory Management

- Dynamic memory allocation and deallocation.

- Prevention of memory leaks through proper memory management.

### String Formatting

- Usage of external functions: `write`, `va_start`, `va_arg`, `va_copy`, `va_end`.

- Mimicking the behavior of the original `printf()` function.

- Handling conversions such as `%c`, `%s`, `%p`, `%d`, `%i`, `%u`, `%x`, `%X`, `%%`.
