Programming Language

Different programming languages ??support different styles of programming (called programming paradigms). The choice of a language depends on many factors, such as company policy, suitability for the task. availability of third-party packages, or personal preference.

Ideally, the programming language best suited to the task is selected. This ideal situation has some drawbacks, such as building a team of sufficient programmers who know the language and the availability of compilers for the language and the executability of programs written in that language. Languages ??

form a spectrum from roughly “low-level” to “high-level”; “low-level” languages ??are typically more machine-oriented and faster to execute, while “high-level” languages ??are more abstract and easier to use, but slower to execute. “High-level” languages ??are generally easier to code in than “low-level” languages. Programming languages ??are essential for software development. They are the fundamental elements of all software, from the simplest to the most sophisticated.

In his book “How to Think Like a Computer Scientist,” Allen Downey writes:

The descriptions may look different in different languages, but some basic instructions are present in almost every language:

Input: Collect data from a keyboard, a file, or another device.
Output: Displaying data on a screen or sending data to a file or other device.
Arithmetic: Perform basic arithmetic operations such as addition and multiplication.
Conditional execution: Check certain conditions and execute the appropriate sequence of statements.
Iteration: Performing an action repeatedly, usually with some variation.

Many computer languages ??provide a mechanism for calling functions provided by shared libraries. Provided that the functions in a library follow appropriate run-time rules (e.g., argument passing), these functions can be written in any other language. The annual ranking by IEEE Spectrum analyzes programming language popularity using metrics such as job postings, search trends, and developer activity.[28]

learning programming

Programming learning has a long history that includes professional standards and practices, educational initiatives and curricula, and commercial books and materials for students, self-taught learners, hobbyists, and others who wish to create or customize software for personal use.

Since the 1960s, programming learning has become a popular movement, encompassing academic disciplines, inspiring leaders, collective identities, and the movement’s growth And strategies have emerged to grow the movement and bring about institutional change. [ 29 ]

Through these social ideals and educational agendas, learning to code has become important not only for scientists and engineers, but also for millions of citizens who have come to believe that creating software is beneficial to society and its members. Participation in computer science education has increased significantly in recent years, with millions of students gaining early programming experience through schools and online platforms.[30]

Context

In 1957, the United States employed approximately 15,000 computer programmers, accounting for 80% of the world’s active developers. In 2014, there were approximately 18.5 million professional programmers worldwide, of whom 11 million could be considered professionals and 7.5 million students or amateurs.[31] Before the rise of the commercial Internet in the mid-1990s, most programmers learned about software construction through books, magazines, user groups, and informal instruction methods. While academic courses and corporate training played an important role for professional employees, [32]

The first book to provide specific instructions on how to program a computer was probably “Preparation of Programs for an Electronic Digital Computer” (1951) by Maurice Wilkes, David Wheeler, and Stanley Gill. This book presented a selection of common subroutines for handling basic tasks on the EDSAC, one of the world’s first stored-program computers.

When high-level languages ??arrived, they were introduced through numerous books and materials that explained language keywords, program flow management, working with data, and other concepts. These languages ??included FLOW-MATIC, COBOL, FORTRAN, ALGOL, Pascal, BASIC, and C. An example of an early programming primer from these years is Marshall H. Wrubel’s A Primer of Programming for Digital Computers (1959). It included step-by-step instructions for filling out coding sheets, creating punch cards, and using keywords in IBM’s early Fortran system.[ 33 ] Daniel McCracken’s A Guide to Fortran Programming (1961) introduced Fortran to a wider audience, including students and office workers.

BE CONTINU

In 1961, Alan Perlis suggested that all freshmen at Carnegie Technical Institute take a course in computer programming. [ 34 ] His advice was published in the popular technical magazine Computers & Automation, which became a regular source of information for professional programmers.

Programmers soon had access to a variety of textbooks to learn from. Programmer’s reference manuals listed keywords and functions related to a language, often alphabetically, as well as technical information about compilers and related systems. An early example was IBM’s Programmer’s Reference Manual: The Fortran Automatic Coding System for the IBM 704 EDPM (1956).

Over time, the genre of programmer’s guides emerged, presenting language features in a tutorial or step-by-step format. Many early guides began with a program called “Hello, World,” which represented the smallest program a developer could create for a given system. Subsequent programmers’ guides discussed core topics such as declaring variables, data types, formulas, flow control, user-defined functions, manipulating data, and other topics.

Early and influential programmer’s guides included John G. Kemeny and Thomas E. Kurtz’s BASIC Programming (1967), Kathleen Jensen and Niklaus Wirth’s The Pascal User Manual and Report (1971), and Brian W. Kernighan and Dennis Ritchie’s The C Programming Language (1978). Similar books for the general reader (but in much simpler language) were Bob Albrecht’s My Computer Loves Me When I Speak BASIC (1972), Al Kelly and Ira Pol’s A Book on C (1984), and Dan Gookin’s C for Dummies (1994).

LET US LEARN ABOUT PROGRAMING

In addition to language-specific introductions, there were numerous books and academic journals that introduced professional programming methods. Many of these were designed for university courses in computer science, software engineering, or related subjects. Donald Knuth’s book “The Art of Computer Programming” (1968 and later) presented hundreds of computational algorithms and their analysis. Brian W. Kernighan and P.J. Plauger’s book The Art of Computer Programming (1968 and later), presented hundreds of computational algorithms and their analysis.

The Elements of Programming Style (1974), by Brian W. Kernighan and P. J. Plauger, concerned itself with programming style, the idea that programs should be written not only to satisfy the compiler but human readers. Jon Bentley’s Programming Pearls (1986) offered practical advice about the art and craft of programming in professional and academic contexts. Texts specifically designed for students included Doug Cooper and Michael Clancy’s Oh Pascal! (1982), Alfred Aho’s Data Structures and Algorithms (1983), and Daniel Watt’s Learning with Logo (1983).
