end program diziler

it gives error like this

C:\Users\Teknik\Desktop\6.odev.F95(8) : error 270 - Missing width count for 'I' descriptor
C:\Users\Teknik\Desktop\6.odev.F95(13) : error 270 - Missing width count for 'F' descriptor

  • sorry for pasting the crappy code – pc fortran Jan 11 '23 at 18:34
  • Is any of the information at https://stackoverflow.com/questions/40797875/fortran-error-with-the-format-statement helpful to you? – Jeff Scott Brown Jan 11 '23 at 18:40
  • We prefer questions to focus on single problems, rather than wanting to address many different compiler errors at once. Here you have two different issues: needing to specify field widths when reading values; using a dynamic (based on runtime value) size for an array. You can find answers to each of these different problems across the linked questions. Specify field widths, or use list-directed input, and use an allocatable array. – francescalus Jan 11 '23 at 18:54
  • Please take the [tour] and see [ask]. Use the code editting features in the question editor. As it stands, the fomatting of your post is completely broken. You cand find more in the [help]. – Vladimir F Героям слава Jan 11 '23 at 19:22
