Array problem

Array problem

Array problem

Hello everyone,

I have a fortran code which reads an ascii file with data of rainfall for the years from 1993 to 2014. I need to count number of dry and wet days in every month. I have posted my code here. I am not getting any error but the code does not count the number of dry and wet days correctly. I don't know what is wrong with my code. Can anyone help me in figuring out this? Thanks in advance.

RE: Array problem

If the data gives the rainfall for the date, then why are you doing range checks on j? You don't even need to read the data into an array. Just do something like this


program wetanddry
integer, parameter:: np=8035
integer rainfall(12), year, month, day, rain
do mm = 1,12
   rainfall(mm) = 0
end do

do i=1,np
   if (rain==-1) then
      rain = 0
      ! are you changing mm to cm?
      rain = 0.1*rain
   end if
   rainfall(month) = rainfall(month) + rain;
end do
do mm = 1, 12
   print  *, 'Month ', mm, ' rain ', rainfall(mm)
end do


RE: Array problem

Thanks for your reply and suggestion. I used array because I need number of rainy days in every month. And the data is available for leap years. So I need to put conditions for leap years and NO leap years.
