+# Jeu de Nim
+
+ Simulation d'une partie de jeu de Nim entre un robot aléatoire et un robot qui connait la stratégie gagnante.
+
+ Ce jeu a été réalisé lors de ma première année de BUT, au sein de la [SAÉ](https://fr.wikipedia.org/wiki/Situation_d%27apprentissage_et_d%27%C3%A9valuation) 1 du premier semestre.
+
+ ### Pour compiler le programme :
+ ```shell
+ gcc -Wall nim.c -o build/nim
+ ```
