Telefon rehberini çekme işlemi While döngüsü sorunu
31.05.2016 - 10:06
izlemiş olduğum bir derste anlatılanı yazdım
ancak her isime tüm numaraların 2 katı kadar rehbere kişi ekleyip gösteriyor
yani 100 kişi varsa a ismini 200 sefer gösteriyor.
Bu sorunun ikinci while dan kaynaklandığını düşünüyorum
ancak konuda yetersiz olduğumdan çözemedim. Bakabilir misiniz.
