A programmer is someone who writes/creates computer software or applications generally by providing instructions (commonly through the use of a specific programming language) to the computer or by configuring already existing code (such as a framework or existing code base). Most programmers have extensive computing and coding experience in many varieties of programming languages and platforms, such as Structured Query Language (SQL), Perl, Extensible Markup Language (XML), PHP, HTML, C, C++ and Java.

A programmer's most often-used computer language (e.g., Assembly, C, C++, C#, JavaScript, Lisp, Python, Java, etc.) may be prefixed to the aforementioned terms. Some who work with web programming languages may also prefix their titles with web.


There is no industry-wide standard terminology, so "programmer" and "software engineer" might refer to the same role at different companies. Most typically, someone with a job title of "programmer" or "software developer" might focus on implementing a detailed specification into computer code, fixing bugs, and performing code reviews. They might have a degree in computer science, an associate degree, or might be self-taught or attended a programming boot camp. Someone with a job title of "software engineer" is expected to understand software engineering principles, more advanced mathematics, and the scientific method, and may be required to have a degree in software engineering, computer engineering, or computer science. Some countries legally require an engineering degree to be called an engineer. In companies that make a distinction, software engineers might have broader and higher-level responsibilities, like designing or architecting new programs, features, and platforms; managing the software development lifecycle including design, implementation, testing, and deployment; leading a team of programmers; communicating with business customers, programmers, and other engineers; considering system stability and quality; and exploring software development methodologies.[1][2][3]


Ada Lovelace is considered by many to be the first computer programmer.[4]

British countess and mathematician Ada Lovelace is often considered to be the first computer programmer, as she was the first to publish part of a program (specifically an algorithm) intended for implementation on Charles Babbage's analytical engine in October 1842. The algorithm was used to calculate Bernoulli numbers.[4] Because Babbage's machine was never completed as a functioning standard in Lovelace's time, she never had the opportunity to see the algorithm in action.

In 1941, German civil engineer Konrad Zuse was the first person to execute a program on a working, program-controlled, electronic computer.[5] From 1943 to 1945, per computer scientist Wolfgang K. Giloi and AI professor Raúl Rojas et al., Zuse created the first, high-level programming language, Plankalkül.[6][7]

Members of the 1945 ENIAC programming team of Kay McNulty, Betty Jennings, Betty Snyder, Marlyn Wescoff, Fran Bilas and Ruth Lichterman have since been credited as the first professional computer programmers.[8][9]

The software industry

The first company founded specifically to provide software products and services was the Computer Usage Company in 1955. Before that time, computers were programmed either by customers or the few commercial computer manufacturers of the time, such as Sperry Rand and IBM.[10]

The software industry expanded in the early 1960s, almost immediately after computers were first sold in mass-produced quantities. Universities, governments, and businesses created a demand for software. Many of these programs were written in-house by full-time staff programmers; some were distributed between users of a particular machine for no charge, while others were sold on a commercial basis. Other firms, such as Computer Sciences Corporation (founded in 1959), also started to grow. Computer manufacturers soon started bundling operating systems, system software and programming environments with their machines; the IBM 1620 came with the 1620 Symbolic Programming System and FORTRAN.[11]

The industry expanded greatly with the rise of the personal computer (PC) in the mid-1970s, which brought computing to the average office worker. In the following years, the PC also helped create a constantly growing market for games, applications and utility software. This resulted in increased demand for software developers for that period of time.[12]

Nature of the work

Computer programmers write, test, debug, and maintain the detailed instructions, called computer programs, that computers must follow to perform their functions. Programmers also conceive, design, and test logical structures for solving problems by computer. Many technical innovations in programming — advanced computing technologies and sophisticated new languages and programming tools — have redefined the role of a programmer and elevated much of the programming work done today. Job titles and descriptions may vary, depending on the organization.[13]

Programmers work in many settings, including corporate information technology (IT) departments, big software companies, small service firms and government entities of all sizes. Many professional programmers also work for consulting companies at client sites as contractors. Licensing is not typically required to work as a programmer, although professional certifications are commonly held by programmers.[13] Programming is considered a profession.[14][15][16]

Programmers' work varies widely depending on the type of business for which they are writing programs. For example, the instructions involved in updating financial records are very different from those required to duplicate conditions on an aircraft for pilots training in a flight simulator. Simple programs can be written in a few hours. More complex ones may require more than a year of work, while others are never considered 'complete' but rather are continuously improved as long as they stay in use. In most cases, several programmers work together as a team under a senior programmer's supervision.[citation needed]

Types of software

Programming editors, also known as source code editors, are text editors that are specifically designed for programmers or developers to write the source code of an application or a program. Most of these editors include features useful for programmers, which may include color syntax highlighting, auto indentation, auto-complete, bracket matching, syntax check, and allows plug-ins. These features aid the users during coding, debugging and testing.[17]


Market changes in the UK

According to BBC News, 17% of computer science students could not find work in their field 6 months after graduation in 2009 which was the highest rate of the university subjects surveyed while 0% of medical students were unemployed in the same survey.[18]

Market changes in the US

After the crash of the dot-com bubble (1999–2001) and the Great Recession (2008), many U.S. programmers were left without work or with lower wages.[19][20] In addition, enrollment in computer-related degrees and other STEM degrees (STEM attrition)[21] in the US has been dropping for years, especially for women,[22] which, according to Beaubouef and Mason,[23] could be attributed to a lack of general interest in science and mathematics and also out of an apparent fear that programming will be subject to the same pressures as manufacturing and agriculture careers. For programmers, the U.S. Bureau of Labor Statistics (BLS) Occupational Outlook originally predicted a growth for programmers of 12 percent from 2010 to 2020[24] and thereafter a decline of -7 percent from 2016 to 2026, a further decline of -9 percent from 2019 to 2029, a decline of -10 percent from 2021 to 2031.[25] and then a decline of -11 percent from 2022 to 2032.[26] Since computer programming can be done from anywhere in the world, companies sometimes hire programmers in countries where wages are lower.[25] However, for software developers BLS projects for 2019 to 2029 a 22% increase in employment, from 1,469,200 to 1,785,200 jobs with a median base salary of $110,000 per year. This prediction is lower than the earlier 2010 to 2020 predicted increase of 30% for software developers.[27][28][20] Though the distinction is somewhat ambiguous, software developers engage in a wider array of aspects of application development and are generally higher skilled than programmers, making outsourcing less of a risk.[29][30] Another reason for the decline for programmers is their skills are being merged with other professions, such as developers, as employers increase the requirements for a position over time. Then there is the additional concern that recent advances in Artificial Intelligence might impact the demand for future generations of Software professions.[31][32][33][34][35][36][37]
