My Fortran Journey

Hello everyone!
I am starting to learn Fortran!
I will update this post with milestones I think are important.
For now however, let's start with update #1.

UPDATE #1:

I wrote my first script in Fortran (Well 2nd I think? But Idc)!

Code: Select all

program strings
    implicit none !Not adding "implicit none" to the beginning of any program written in Fortran is considered bad because it hides a lot of information, causing more errors
    
    character(len=8) :: forum !creates a variable named "forum"
    
    forum = 'T2Oboard' !sets "forum" to "T2Oboard"
    
    print *, 'Hello Fortran!' !Hello Fortran!
    print *, forum, 'is awesome!' !T2Oboard is awesome!
end program strings
I'm using this site...
https://fortran-lang.org/
... to learn Fortran, and this site...
https://dev.lfortran.org/
... to practice.

END OF UPDATE #1


UPDATE #2

I wrote a program showcasing what I've learned of do loops!

Code: Select all

program say_100_times
    implicit none
    character(len=50) :: saywhat
    integer :: i !declares the integer of how many times the do loop shall repeat; in this case, 100
    
    
    print *, 'What do you want me to say 100 times? (Character limit: 50)'
    read (*,'(A)') saywhat !asks for the string to repeat 100 times
    
    do i = 1, 100 !initializes the do loop and specifies its limit (1-100)
    print *, trim(saywhat) !trim(saywhat) removes unnecessary space
end do !ends the do loop, obviously
    print *, 'Finished! Exiting...'
end program say_100_times
END OF UPDATE #2


UPDATE #3

I wrote a "mad libs" style program!

Code: Select all

program story
    implicit none
    character(len=5) :: w1, w2, w3, w4 !declares our inputs
    
    print *, "Let's write a story! I'll prompt you for some words; type them into the space provided" !some of the print functions here have to be "" instead of '' because using words with apostrophes end the print function early
    print *, "and hit enter to finalize your input."
    print *, "REMEMBER: You cannot change your choice once you hit enter, so please make sure"
    print *, "that you're happy with it."
    print *, "Also: you have to type a word with 4-5 letters (To avoid trailing spaces)."
    print *, "Ready? Let's begin!"
    print *, '' !blank lines for space
    print *, '' !blank lines for space
    print *, "Enter a word representing onomatopoeia, make sure it's uppercase..."
    read(*,*) w1 !this function (and other subsequent functions similar to this) updates our word bank of inputted words
    print *, 'Enter a noun...'
    read(*,*) w2
    print *, 'Enter a verb ending in ed, but do not type the ed...' !this is because the "ed" is already printed at the end
    read(*,*) w3
    print *, 'Enter a location...'
    read(*,*) w4
    print *, ''
    print *, ''
    
    print *, w1,  '! The ', w2, ' ', w3, 'ed through the ', w4, '.'  !puts the story together
end program story

I tried to run loop and it did not work :cry:

What are you running it on?
