Klasslar

Klass – bu dasturchi tomonidan ixtiyoriy kiritilgan mavjud tiplar asosida yaratilgan strukturalangan toifa hisoblanadi. Klasslar lokal va global o‘zgaruvchilar va ular ustida amal bajaradigan funksiyalar to‘plamidan iborat bo‘lishi mumkin. Klasslar quyidagicha tasvirlanadi:

class klass_nomi{
