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 text,
distributed in such a way as to represent each problem type in each chapter while favoring
easy problems and early chapters. Chapter 3 of this Manual contains some additional
exercises and their solutions. Chapter 4 contains some materials that I have found useful
in teaching programming from Classical FORTRAN.
