Daha sonra delete fonksiyonunu kullanarak (ana menuden 5 girerek) bu girdiğim kaydı silmek icin oraya tekrar atama yapmak istiyorum. (Ad, soyad ve numara 0 degerine ya da NULL değerine eşit olsun diye uğraşıyorum) Ancak ne denediysem atamayı delete fonksiyonu icersinde bir turlu yapamadım. Kod satırlarında ((( deletE() fonksiyonunda ))) yaptığım atamalara (// olarak yorum satırlarında) bakabilirsiniz.
Acaba nasıl atama yapılmalı ?
