Computer Programming In Fortran 77

This is a revised and enlarged version of the author's book which received wide acclamations in its earlier three editions. It provides a lucid and in-depth introduction to the programming language Fortran 77 which is widely used by scientists and engineers.The fourth edition is completely revised chapterwise and also minor corrections incorporated. A new standard for Fortran called Fortran 90 was introduced in early 90s and compilers for this version of Fortran were sold in early 1995 by computer vendors. All Fortran 77 programs will run without change with Fortran 90 compilers; however some aspects of Fortran 77 have been declared obsolete and will not run on future Fortran compilers_these are explained in this revised edition. An appendix consolidates these features. Fortran 90 is introduced in a new chapter which summarises all its features.

The complete guide to computer programming with FORTRAN 77, the cost effective workhorse among programming languages for scientific and engineering work. FORTRAN 77 retains the efficiency of FORTRAN IV while being a more elegant language. The text is written for the beginner without previous computer experience.

This book introduces Computer Programming to a beginner, using Fortran 90 and its recent extension Fortran 95. While Fortran 77 has been used for many years and is currently very popular, computer scientists have been seriously concerned about good programming practice to promote development of reliable programs. Thus, the International Standards Organization set up a group to 'modernise' Fortran and introduce new features which have made languages such as Pascal and C popular. The committee took over a decade to come up with the new standard, Fortran 90. Fortran 90 has introduced many new features in Fortran, such as recursion, pointers, user-defined data types etc., which were hitherto available only in languages such as Pascal and C. Fortran 90 is not an evolutionary change of Fortran 77 but is drastically different. Though Fortran 77 programs can be run using a Fortran 90 compiler, Fortran 90 is so different that the author felt it was not a good idea to just revise Fortran 77 and introduce Fortran 90 in some places in the book. Thus this book is entirely new and introduces Fortran 90 from basics. In 1996 some small extensions were made to Fortran 90 and has called Fortran 95. This book also discusses these features. As all new programs in Fortran will henceforth be written in Fortran 90, it is essential for students to learn this language.The methodology of presentation, however, closely follows the one used by the author in his popular book on Fortran 77.

Offering a clear tutorial guide for the new Fortran 90 language, this book highlights Fortran 90's role as a powerful tool for problem-solving in engineering and science. Having been involved in the development of the new standard, the authors provide (as a bonus) an inside perspective on the design rationale behind the major features of Fortran 90.Features comprehensive coverage of all the major language features, with clear guidelines on the differences between the 77 and 90 standards case studies illustrating its applications in scientific problem-solving two authoritative chapters in coding numerical methods in Fortran 90 an early introduction to procedures and modules to encourage a structural approach to programming 0201544466B04062001

A comprehensive introduction which will be essential to the complete beginner who wants to learn the fundamentals of programming using a modern, powerful and expressive language; as well as those wanting to update their programming skills by making the move from earlier versions of Fortran.
