A Fortran 2003 introduction by examples Gunnar Wollan 2012 1 Introduction The purpose of this book is to give a good insight in the Fortran 2003 program-ming language.by going through a number of examples showing how computa-tional problems and the reading and writing data to files can b e solved. We refer to variables in Fortran as having certain Types. In the last 15 to 20 years Fortran has been looked upon as an old … We start by looking at a simple example where we calculate the area of a circle: program circle real r, area c This program reads a real number r and prints c the area of a circle with radius r. write (*,*) 'Give radius r:' Example of a Fortran 90 Program. When the black output window opens right click on the Plato icon in the top left corner . READ *, a, b, c PRINT *, 'Triangle''s area: ', Area(a,b,c) END PROGRAM Triangle FUNCTION Area(x,y,z) IMPLICIT NONE REAL :: Area ! 2 Why use Fortran? Fortran permet d’initialiser une variable lors de sa déclaration à l’aide du symbole «=» I Dans ce cas, les caractères: :sont obligatoires I Ces variables héritent aussi de l’attributSAVE Exemples REAL a,b, c INTEGER n DATA a,b,n/1.0 , 2.0 , 17/ LOGICAL: : flag = .TRUE. An example might be a program that asks people questions, including things like their age and name and so on. A type describes what kind of data the variable is expected to contain. It could, for example, print out their year of birth with a suitable message. Fortran - Modules - A module is like a package where you can keep your functions and subroutines, in case you are writing a very big program, or your functions or subroutines can b FORTRAN 90 Matmeca 1`ere ann´ee ENSEIRB-MATMECA Luc Mieussens Luc.Mieussens@math.u-bordeaux1.fr - ´equipe Calcul Scientifique et Mod´elisation - Institut de Math´ematiques de Bordeaux Universit´e de Bordeaux version du 28 septembre 2011 1. Consider the following example Fortran 90 program: PROGRAM Triangle IMPLICIT NONE REAL :: a, b, c, Area PRINT *, 'Welcome, please enter the& &lengths of the 3 sides.' A Fortran program is just a sequence of lines of text. For example, the expression x = 3 we could say that x … Variables can also be used to store non-numeric values such as text, letters, and words, for example. The best text and video tutorials to provide simple and easy learning of various technical and non-technical subjects with suitable examples and code snippets. The text has to follow a certain syntax to be a valid Fortran program. It's up to you, just use your imagination. Violaine Louvet (CNRS/ICJ) Fortran Rabat, 9-12/04/2012 19 / 105. Le but de ce cours est d’apprendre `a programmer en fortran 90. Saving the contents of Output Window. Run your last program again.
