Tufan Bey merhaba,
Gonderdiginiz programda bircok sorun var ve icinde pek de dokumantasyon
yok, bu sebeple bir sey soylemek guc. Ancak su genel tavsiyeyi
verebilirim; programinizi gcc'ye -Wall parametresini vererek tekrar
derlerseniz, yani
gcc -Wall server.c -o server
gcc -Wall client.c -o client
seklinde, derleyici size bir takim tuyolar verecektir. Bunlara dikkat
ettiginizde bir hayli yol katedeceginize eminim. Eger hala sorun
cozulmezse, daha fazla dokumantasyonla beraber (ornegin client ne yapar,
server ne yapar) duzeltilmis kodunuzu tekrar gonderirseniz yardimci
olmaya calisiriz.
Iyi calismalar,
emre
