How to Download and Install Fortran 90 Compiler for Windows 7 for Free
Fortran 90 is a programming language that is widely used for scientific and numerical computing. It is a standardized version of Fortran that supports modern features such as modules, arrays, pointers, and dynamic memory allocation. Fortran 90 is still popular among researchers and engineers who need to write efficient and portable code for high-performance computing.
If you want to use Fortran 90 on your Windows 7 computer, you will need a compiler that can translate your source code into executable files. A compiler is a software tool that converts your human-readable code into machine-readable instructions that can run on your computer. There are many Fortran 90 compilers available for Windows 7, but not all of them are free. In this article, we will show you how to download and install one of the best free Fortran 90 compilers for Windows 7: GNU Fortran.
What is GNU Fortran?
GNU Fortran, also known as GFortran, is a free and open-source Fortran compiler that is part of GCC, the GNU Compiler Collection. GCC is a set of compilers for various programming languages, such as C, C++, Java, Ada, and Fortran. GCC is widely used by developers and programmers around the world because it is reliable, fast, and compatible with many platforms and standards.
GFortran supports most of the Fortran standards, including Fortran 95, 2003, 2008, and 2018. It also supports some extensions and features from other compilers, such as g77 and Intel Fortran. GFortran can produce optimized and high-quality code for various architectures and environments. It also has good diagnostics and debugging features that can help you find and fix errors in your code.
How to Download GNU Fortran for Windows 7?
GNU Fortran is not available as a standalone program for Windows 7. You will need to download GCC, which includes GFortran and other compilers. However, GCC does not have an official binary distribution for Windows 7. You will need to use a third-party installer that can provide you with a pre-compiled version of GCC for Windows 7.
One of the most popular and reliable installers for GCC on Windows 7 is MinGW-w64. MinGW-w64 is a project that aims to provide a complete runtime environment for GCC on Windows systems. It includes not only the compilers but also the libraries, headers, tools, and utilities that are needed to run GCC on Windows. MinGW-w64 supports both 32-bit and 64-bit versions of Windows.
To download MinGW-w64 for Windows 7, you can follow these steps:
Go to the official website of MinGW-w64: https://www.mingw-w64.org/
Click on the "Downloads" tab on the top menu.
Under the "SourceForge" section, click on the link that says "Mingw-w64 - for 32 and 64 bit Windows". This will take you to the SourceForge page of MinGW-w64.
On the SourceForge page, click on the green button that says "Download". This will start downloading a file named "mingw-w64-install.exe". Save this file to your computer.
How to Install GNU Fortran for Windows 7?
Once you have downloaded MinGW-w64 for Windows 7, you can install it by following these steps:
Double-click on the file "mingw-w64-install.exe" that you have downloaded. This will launch the MinGW-w64 installer.
Select your preferred language and click "OK".
On the welcome screen, click "Next".
On the license agreement screen, read the terms and conditions and click "I Agree" if you accept them.
On the installation settings screen, choose the following options:
Version: Select the latest version available (e.g., 8.1.0).
Architecture: Select either "i686" or "x86_64" depending on whether you have a 32-bit or a 64-bit version of Windows 7.
Threads: Select either "posix" or "win32" depending on whether you want to use POSIX or Windows threads.
Exception: Select either "dwarf" or "sjlj" depending on whether you want to use DWARF or SJLJ exception handling.
Build revision: Select any number (e.g., 0).
Click "Next".
On the destination folder screen, choose where you want to install MinGW-w64 on your computer. The default location is "C:\Program Files\mingw-w64". You can change it if you want.
Click "Next".
The installation will begin. Wait until it finishes.
Click "Finish".
How to Use GNU Fortran on Windows 7?
To use GNU Fortran on Windows 7, you will need to open a command prompt window and type some commands. You can do this by following these steps:
Click on the Start button on your desktop.
Type "cmd" in the search box and press Enter. This will open a command prompt window.
In the command prompt window, type "cd C:\Program Files\mingw-w64\mingw32\bin" (or whatever location you have installed MinGW-w64) and press Enter. This will change your current directory to where GFortran is located.
To compile a Fortran source file named "hello.f90", type "gfortran hello.f90 -o hello.exe" and press Enter. This will create an executable file named "hello.exe" in the same directory.
To run the executable file named "hello.exe", type ".\hello.exe" and press Enter. This will run your program and display its output.
Congratulations! You have successfully downloaded, installed, and used GNU Fortran on Windows 7 for free!
Advantages and Disadvantages of Fortran 90
Fortran 90 is a programming language that is widely used for scientific and numerical computing. It is a standardized version of Fortran that supports modern features such as modules, arrays, pointers, and dynamic memory allocation. Fortran 90 is still popular among researchers and engineers who need to write efficient and portable code for high-performance computing.
However, like any other programming language, Fortran 90 also has its advantages and disadvantages. Here are some of them:
Advantages
It is compatible with Fortran 77, which means that most of the existing Fortran code can be compiled and run with Fortran 90 compilers.
It has improved syntax and features that make the code more readable, concise, and expressive. For example, it supports array operations, implicit loops, user-defined types, recursion, generic procedures, etc.
It has better support for parallel processing and distributed computing, which can enhance the performance and scalability of the code.
It has better error detection and handling mechanisms, such as modules, interfaces, derived types, etc., that can help prevent and fix bugs.
It has many standard libraries and tools that provide useful functions and routines for various domains and applications.
Disadvantages
It is not as widely used or supported as some other programming languages, such as C or Python, which means that it may have less resources, documentation, community, and updates available.
It may not be as easy or intuitive to learn or use as some other programming languages, especially for beginners or non-programmers.
It may not have as many features or capabilities as some other programming languages, such as object-oriented programming, functional programming, graphical user interface, etc.
It may have some compatibility or portability issues with different compilers, platforms, or standards.
It may have some performance or efficiency drawbacks compared to some other programming languages, depending on the implementation and optimization of the code.
These are some of the advantages and disadvantages of Fortran 90. You can weigh them and decide whether this programming language is suitable for your needs or not.
Examples of Fortran 90 Programs
Fortran 90 is a programming language that is widely used for scientific and numerical computing. It is a standardized version of Fortran that supports modern features such as modules, arrays, pointers, and dynamic memory allocation. Fortran 90 is still popular among researchers and engineers who need to write efficient and portable code for high-performance computing.
To help you learn and practice Fortran 90, here are some examples of simple programs that demonstrate some of the features and capabilities of the language. You can try to compile and run these programs using any Fortran 90 compiler that you have access to.
Example 1: Hello World
This program prints the message "Hello, world!" to the standard output.
program hello
implicit none
print *, "Hello, world!"
end program hello
Example 2: Area of a Triangle
This program calculates the area of a triangle using Heron's formula. It reads the lengths of the three sides from the standard input and prints the area to the standard output.
program triangle
implicit none
real :: a, b, c, s, area
print *, "Enter the lengths of the three sides:"
read *, a, b, c
s = (a + b + c) / 2.0
area = sqrt(s * (s - a) * (s - b) * (s - c))
print *, "The area of the triangle is:", area
end program triangle
