Delphi tilida test dasturini yaratish texnologiyasi

Biz Delphi dasturlash tilida tesdasturini yaratish uchun bizga test dasturi uchun bloknotda sovol tuzib olamiz bunda 1 fanning nomi 2 savollar soni misol uchun 5 ta savol uchun 5 raqam yoziladi 3 vaqt misol uchun 1 minut uchun 1:00 yoziladi savollar ketma-ketligi qatorma-qator yoziladi to’g’ri javobga 1,2,3,4 sonlar qo’yiladi agarda javoblar 4 tadan iborat bo’lsa, savoldan keying 1 qatordagi javob to’g’ri bo’lsa, 1 raqam qo’yiladi va ikkinchi savol boshlanadi va shu ketma-ketlik davom ettiriladi savolning javobini ixtiyoriy qatorga qo’yish mumkin.

Rasm 1.

Delphida dasturi dizayni quyidagicha berilgan.

Fayl bo'limidan testni yuklaymiz rasm 3.

Dastur bajarilish dizayni rasm 4.

Dasturi kodi quyidagicha
