11. N ta birinchi tub sonning qiymati ListBoxga yozing
12. Bitta ListBoxda quyidagicha elementlar bo’lsin:
Misol: 1 2 3 4 5
Natija sifatida ikkinchi listboxga uni ikki martadan yozing:
Natija: 1 1 2 2 3 3 4 4 5 5
13. N ta xodimning maoshlari qiymati ma’lum (ListBoxda). Z summadan katta maosh oluvchi xodimlarnining maoshlari hammasi Z ga almashtirilsin. (Yangi ListBoxda)
14. N ta xodimning maoshlari qiymati ma’lum (ListBoxda). Eng katta maosh oluvchi
xodimning maoshi eng kam maosh oluvchi xodimning maoshidan necha barobar katta
ekanligini aniqlang. Natija Label da chip etilsin.
