Libft

Description

Libft is a static library project where commonly used standard functions are reimplemented in the C language. The purpose of the project is to learn the basic structures of C, memory management, pointer usage, and the fundamentals of programming logic.

Instructions

Compilation

To compile the library, use the following command:

make

As a result, a static library named libft.a is created, allowing the written functions to be used in other projects.

Cleaning

To remove object (.o) files:

make clean

To remove object files together with the libft.a file:

make fclean

To remove everything and rebuild the project from scratch:

make re

Library Contents

libft.a contains the following functions:

Character Check Functions

Usage

To use the library in another project:

cc main.c libft.a

or:

cc main.c -L. -lft

The header file must be included in the source file:

#include "libft.h"

Resources

• man pages

Use of Artificial Intelligence

During this project, artificial intelligence tools were used for:

• Understanding the C compilation process (compile, assemble, link)
• Learning the structure of a Makefile
• Explaining the behavior of standard C functions

All function implementations and final decisions were made by the project owner.
