Fortran 90 Basics

Here we present some codes to learn the structure and first useful commands in Fortran 90 language

Table of Contents

Code	Content
code0_structure.f90	We introduce the standard structure used in all codes in Fortran 90 programming language
code1_variable	We display how to declare and handle variables like 'integer','real', 'complex' and 'array' (vector and matrix)
code2_functions.f90	We introduce how to use 'functions' to make our codes more efficient
code3_routines.f90	We introduce how to use 'subroutines' to make our codes more efficient, even more than 'functions'
code4_loops.f90	We display the most usual structures of iteration and decision, like 'do', 'do while', 'else', 'if' and 'continue'
code5_write-read_files.f90	We show how to write and to read data in 'txt', '.fort' extensions and even at the 'terminal'
code6_modules.f90	We present how to use global variables using the structure 'module'
