Bonjour,
Je suis très débutant en C et après avoir regardé différents tuto et forums je n'ai toujours pas trouvé la solution à mon problème.
J'ai des fichiers .txt contenant des valeurs numériques que je souhaite extraire et mettre dans un tableau à deux dimensions pour y accéder facilement et les exploiter dans les calculs.
Voilà quelques extraits des fichiers en question :

Mon idée est de parcourir le fichier et de replacer la j-ème valeur de la i-ème ligne à la même place (tab[i][j]) dans un tableau de deux dimensions.
Initialement j'avais imaginé utiliser fscanf mais comme mon fichier a 241 valeurs par lignes (et 121 lignes) mais je me voyais mal écrire un truc du genre fscanf(file,%f%f...%f,var1 var2...var241).
En fouillant un peu j'ai vu qu'on pouvait utiliser fseek pour décider de l'endroit où on place le "curseur" mais j'ai cru comprendre qu'on le déplaçait caractère par caractère et ça ne m'aide pas beaucoup plus...
Enfin j'ai vu qu'il existait aussi la commande fgets mais comme il faut connaître le nombre de caractère à lire je ne sais pas si c'est très adapté à mon cas.
Bref, vous aurez compris que je rame un peu (hum hum même un peu plus que ça), et que j'aurais bien besoin de vos conseils.
Merci d'avance pour votre aide !!
