+It uses ncurses to display a randomly generated view that follows the rules of the Game Of Life.

+## Usage
+
+Just compile it using gcc with -ncurses argument :
+
+<code>gcc -ncurses main.c</code>
+
+Then, you can launch it with an argument giving the initial percentage of alive cells :
+
+<code>./a.out density</code> (where density is in [|0,100|])
