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.

Rasm 1.
Delphida dasturi dizayni quyidagicha berilgan.

Rasm 2.
Fayl bo'limidan testni yuklaymiz rasm 3.

Rasm 3.
Dastur bajarilish dizayni rasm 4.

Rasm 4.
