File 1
S qator berilgan.Agar S yaroqli fayl nomi bo’lsa , u holda shu nom bilan bo’sh fayl yarating va TRUE deb chop eting.Agar S nomli fayl yaratilmasa ,FALSE deb chop eting.
Kod (Python)
file_name = input('Fayl nomini kiriting: ')
try:
f = open(file_name, "w")
try:
f.write('')
print('TRUE')
finally:
f.close()
except IOError:
print('FALSE')
File 2
Fayl nomi va N(>1) butun soni berilgan.Berilgan nomli butun sonlardan iborat fayl yarating va unga birinchi N musbat juft sonni (2,4,6 …) yozing.
Kod (C/C++)
#include

File 3
Fayl nomi va haqiqiy sonlar A va D berilgan.Berilgan nomli haqiqiy sonlar faylini tuzing va unga arifmetik progressiyaning dastlabki 10 a’zosini A boshlang’ich a’zosi va D farqi bilan yozing:A,A+D, A + 2·D, A + 3·D, ...
Kod (Python)
