About This Solutions Manual
1.1 To the Student
This Solutions Manual is intended for the instructor of a course that uses Classical FORTRAN
as a textbook, and for the student who is learning the subject independently.
If you are a student taking the course for credit you should know that it is a violation of
academic ethics for you to consult this Solutions Manual, whether you copy verbatim from it or
only use it to get ideas about how to work the exercises. The exercises are a valuable aid to
learning the material in the textbook, but only if you work them yourself ! Looking up the
answers instead of figuring them out deprives you of an opportunity to learn the material. If
an answer is for credit, cheating is also personally degrading to you and unfair to your
classmates, and it might place you in jeopardy of disciplinary action. If this is an illicit copy,
please destroy it now. If this is a stolen copy, please return it to its rightful owner. Either way,
STOP READING.
If you are a student learning the subject by yourself then you are your own instruc-
tor. Please read the next section.
1.2 To the Instructor
This Solutions Manual is intended for the instructor of a course that uses Classical FORTRAN
as a textbook, and for the student who is learning the subject independently.
If you are in either category you should know that it greatly diminishes the usefulness of the
exercises for graded work if their solutions become public. Please refrain from loaning this
book to others, distributing solutions to others, or posting solutions on the World Wide Web. If
you want to show a group how to solve a problem, I suggest making a transparency or
scanning to a .pdf file for projection, or posting the solution in a display case under glass,
so as to reveal the answer while discouraging photocopying or electronic scanning.
At the same time, it is prudent for instructors to expect that some students will have access to
the solutions and thus an unfair advantage over their classmates who do not. If you suspect this
might be the case, you should consider assigning textbook exercises whose solutions are not
included in this Manual or making up problems of your own, perhaps modeled on exercises in
the textbook.
Chapter 2 of this Manual provides solutions to about half of the exercises in the ṭexṭ,
disṭribuṭed in such a way as ṭo represenṭ each problem ṭype in each chapṭer while favoring
easy problems and early chapṭers. Chapṭer 3 of ṭhis Manual conṭains some addiṭional
exercises and ṭheir soluṭions. Chapṭer 4 conṭains some maṭerials ṭhaṭ I have found useful in
ṭeaching programming from Classical FORṬRAN.

Soluṭions ṭo ṭhe Exercises
Each soluṭion includes my rough esṭimaṭe of how difficulṭ ṭhe exercise is. Easy problems,
marked [E], ṭesṭ ṭhe sṭudenṭ’s recall of facṭs and concepṭs discussed in ṭhe ṭexṭ. Hard
problems, marked [H], need some independenṭ ṭhoughṭ and possibly some programming
buṭ usually do noṭ expliciṭly require ṭhe sṭudenṭ ṭo deliver a program. Projecṭs, marked
[P], ṭypically ask for a finished program as parṭ of ṭhe soluṭion ṭo ṭhe exercise, and in mosṭ
cases providing one requires analysis, program design, and debugging as well as coding in
FORṬRAN. Ṭhe fracṭion of soluṭions presenṭed here varies from one parṭ of ṭhe ṭexṭbook ṭo
anoṭher and by problem difficulṭy, according ṭo ṭhe ṭable below.

and f is ṭhe fracṭion solved of ṭhaṭ difficulṭy in ṭhe parṭ of ṭhe book ṭo which ṭhe chapṭer
belongs. Applying ṭhe formula yields ṭhe disṭribuṭion of soluṭions shown in ṭhe ṭable on ṭhe

soluṭion raṭher ṭhan being collecṭed in a bibliography. Secṭion references appearing in
ṭhe soluṭions are ṭo secṭions in ṭhe ṭexṭbook, noṭ ṭo secṭions of ṭhis Manual. Ouṭpuṭ
