Variant № 23
. 1. Berilgan S satrdagi “a” xarfi qatnashmagan so’zlar sonini qaytaruvchi ASizSuzlarSoni(S) metodini yarating. Delegat yordamida metoddan foydalanib matndagi “a” xarfi qatnashmagan so’zlar sonini chiqaruvchi dastur tuzing.
2. Viloyat nomli (ID, Nomi, Maydoni, ShaharSoni, TumanSoni maydonlarga ega) class yarating. 6 ta viloyatdan iborat ro’yxat tuzing. Ro’yxatni TumanSoni bo’yicha saralab chiqaruvchi dastur tuzing.
