Fortran

Course Description

In this five-day hands-on course students learn how to read, write, and debug complex Fortan programs.

Course Objectives

Upon successful completion of this course, students will be able to:

• Read and understand Fortran programs
• Debug Fortran programs
• Create interactive Fortran programs
• Use all key features Fortran: arrays, branches, loops, subroutines, functions, etc.
• Write Fortran programs that solve complex mathematical, scientific, and engineering problems

Course Benefits

Fortran is a general purpose programming language ideally suited for numeric and scientific computing. In this course, students learn how to read, write and debug Fortran programs. By learning Fortran programming students will be able to write, support, and enhance many important computer programs written in Fortran. Students also gain an understanding of programming principles.

Who Should Attend

This course is valuable for anyone who has been tasked with revising, building, managing, supporting, or maintaining a Fortran programming project, and anyone who needs to learn Fortran.

Prerequisite

To ensure success, we recommend students taking this course have a basic knowledge of computer use and terms, and keyboard skills.

Method Of Instruction

Lecture, demonstrations, questions and answers, and numerous hands-on exercises.
