🗣️ About

The aim of this project is to make you code a function that returns a line ending with a newline, read from a file.

For detailed information, refer to the subject of this project.

🚀 TLDR: This project consists of graphically creating a schematic representation of a relief terrain.

🛠️ Usage

Requirements

The function is written in C language and thus needs the gcc compiler and some standard C libraries to run.

Instructions

1. Installation

In order to install the fdf, you need to clone it:

git clone https://github.com/RochBlondiaux/Fdf.git && cd Fdf

Then, compile it with make:

make

2. Usage

It's really simple, you just have to execute this command:

./fdf my_map.fdf

The program only accept .fdf files, you can use maps from the maps/ folder, create your owns or even generate them with 42MapGenerator.
