Category: Introduction to Fortran Programming

Fortran, one of the oldest high-level programming languages, is widely used in scientific computing, engineering simulations, and numerical analysis. Among the fundamental concepts in Fortran programming are variables, which are used to store data. One of the most basic yet powerful types of variables in Fortran is the integer variable. Integer variables store whole numbers…

Fortran is a high-performance programming language extensively used in scientific computing, numerical simulations, and engineering applications. While traditional Fortran programs were often monolithic and procedural, modern Fortran emphasizes modularity, readability, and maintainability. One of the most powerful features of modern Fortran is the module, which allows developers to organize code, encapsulate functionality, and enable code…

File handling is a fundamental part of programming that allows a program to read from and write to files. Fortran, being a powerful scientific and engineering programming language, provides robust support for file operations. These operations include opening files, reading data, writing data, and closing files. Proper file handling ensures data persistence, reusability, and efficient…

Input and output (I/O) operations are essential in any programming language. They allow programs to interact with users, read data from files, and display results. In Fortran, input and output operations are performed using commands like read, print, and write. This post will explore these commands in detail, along with practical examples and best practices…

Fortran, one of the earliest high-level programming languages, was specifically designed for numerical and scientific computation. To write modular, maintainable, and reusable code, Fortran provides functions and subroutines. These two constructs allow programmers to organize programs into logical blocks that perform specific tasks. Understanding the differences between functions and subroutines and how to implement them…

Arrays are one of the most important data structures in Fortran, particularly in scientific and numerical computing. An array is a collection of elements, all of the same data type, stored in contiguous memory locations and accessed using indices. Arrays simplify the storage and manipulation of large sets of data, such as measurements, simulation results,…

Fortran, one of the earliest programming languages, is still widely used in scientific computing, numerical analysis, and engineering applications. Loops are fundamental constructs in Fortran that allow repeated execution of a block of code. Fortran primarily supports two types of loops: DO loops (count-controlled loops) and DO WHILE loops (condition-controlled loops). Understanding these loops is…

Control structures are fundamental building blocks in programming. They allow the programmer to dictate the flow of a program based on certain conditions. One of the most widely used control structures is the IF statement. IF statements are used to execute a block of code only when a specified condition is true. 1. Introduction to…

In programming, operators and expressions form the foundation of computations. They allow us to manipulate data, make decisions, and control the flow of a program. Fortran, being one of the oldest high-level programming languages, provides a robust set of operators and expression handling mechanisms. This post will explore these in detail with examples and explanations.…

Fortran, which stands for Formula Translation, is one of the oldest high-level programming languages, primarily designed for numerical and scientific computing. One of the fundamental concepts in Fortran programming is the use of variables and data types. Proper understanding and usage of variables and data types are crucial for writing efficient and error-free programs. This…
