What is Computer Programming?
Computer programming is the process of designing and developing various computer programs to complete specific tasks in either application or software or within the computers. The process constitutes many tasks, like analyzing the problem, generating an algorithm to solve it, and then examining the output generated. Computer programming is creating a series of programs to resolve a problem in a computer.
The whole procedure of writing computer programs is called Computing Programming. The programming also has another name called "coding" and the person who writes the code is referred as the "Programmer" or "Coder". Programming is inputting instructions to the computer or machines that describe how to carry out a task. Programmers use various programming languages to code the different parts of the system, like software, hardware, and applications in computers and digital devices, which helps us use them for many tasks. There are various programming languages to write programs which include:
Why do we need programming?
The main goal of programming is to make tasks easier because if we program a task for one time, we can reuse it in many similar situations, saving time. With the help of programming, only machines can understand user-given commands. Computer programming will impact the future by creating even more automated processes requiring less human interaction.
Banking from any location is possible only by programming. For example, consider an online banking website or application which opens a user portal from which the applicants can make transactions using a smartphone or computer; by this, we can save time, energy, and physical work of going to the bank for every small need.
Apart from the advantage mentioned above, we can also make our carrier in programming, which is a huge demand nowadays.
There are various groups of programming languages. Let us discuss some of them on this page, described below.
Different types of Programming Languages
Low-Level Programming Languages
Low-level programming languages again consists of machine-level languages and assembly-level languages.
Middle-Level Programming Languages
Middle-level programming languages are the programming languages that have characteristics of both low-level and high-level languages.
C Language - The c programming language acts as a mediator between hardware and programming layer. C is easy to understand and flexible. It is a compiled language and does not use objects and classes. Compilers and editors use C to design their applications.
High-Level Programming Languages
A declarative language is a programming language where the programmers concentrate on the goal or result of the program. They need to pay attention to achieve a goal. These languages check the relationship among the statements and use deduction, induction, and abduction to give the output.
An example for a declarative language is "PROLOG," which is similar to SQL(Structured Query Language) and works by evaluating logical statements.
Display languages are the languages that are used for displaying content on web pages. The mostly used display languages are HTML, XML, and PHP.
Document Formatting Languages
Document Formatting Languages are the programming languages that help manage the printed text and graphics of a particular page in a document. The language may come under various groups like text formatting, page description language, or markup language.
Examples of Document Formatting Languages are TeX, PostScript, and SGML.
Functional languages are programming languages in which the bigger functions are divided into smaller functions to solve complex problems. Examples of functional languages are Java and Haskell.
Computer Programming and its uses
Computer programs solve many problems and create something innovative in various fields like agriculture, education, entertainment, etc.
Computer Programmers responsibilities
The procedure of developing the program from scratch to deployment involves many steps, which are described as follows:
Skills and requirements for a Programmer
Categories of Programming jobs
These web developers are also categorized into three types, namely backend, front-end, and full-stack developers.
Full-stack developers = Front-end developer + Backend developer.
Web admins are also web developers who manage websites regularly. They are the persons who update the websites and links of the web pages to redirect the users to the appropriate page according to their requirements.
The app developer designs, develop, and implement mobile applications. Mobile developers build applications for mobile phones (like smartphones and tablets). They are specialized in mobile technology and build applications for Android, Apple(iOS applications), and Microsoft Windows Phone platforms. The developers can use the android studio application to build the android apps using JavaJava, Kotlin, and flutter languages. Mobile developers also develop IOS applications for macOS. Mobile developers are in huge demand because every person, from students to older people, uses smartphones and their applications to meet their requirements.
Mobile developers should have good programming skills, especially related to object-oriented concepts and problem-solving knowledge, so they try to build better applications that are helpful for everyone.
The game developers build games compatible with mobiles, laptops, and desktops. They will develop new ideas and build better games that may be related to education and entertainment. They will make code from the ideas, which is a very creative task. These games can be simple to create and some are even more complex to design and develop.
Designing skills, creativity, cognitive and analytical thinking, animation, computing, and problem-solving skills are very important for game developers.
Computer System Engineer
Computer systems engineering includes designing computer networks, assembling and managing networks and traffic for individuals and organizations, and managing software and hardware components of computing systems. Computer system engineering includes various interdisciplinary fields like computer science, electronic engineering, and mathematical analysis.
Computer System Engineers have much respect and need in government, transportation, and Telecommunications industries to maintain the huge traffic and networks and maintain the information flow between the senders and receivers.
The database administrator maintains and operates the database. In these, the Database architects design and develop the programs to meet the user requirements. They secure them from various types of attacks.
What is the variation between computer programmers and software developers?
Software engineers are also computer programmers who program for a specific domain. The software developers will think in depth about a project, like the design and features of an application they are going to develop.
The programmers will write code for a specific problem rather than create a whole project or website.
The software developers will create a featured application to meet the client's needs using many concepts like object-oriented programming, functional programming, etc. But the programmers will not consider the clients as they will not design the complete application. The programmer always aims to deliver code for a particular problem instance.
The software developers will know computer programming, but only some of the programmers can be software developers.
What is the difference between Computer Science and Computer Programming?
Computer programming includes creating and developing code to build new things to eliminate problems and bring solutions by creating applications. The job roles under the computer programming categories are software developer, web developer, mobile application developer, and quality assurance(QA) analyst.
Coming to computer science is a field with no application development but involves solving problems by applying abstract algorithms. Computer scientists develop ideas, and then computer programmers implement those ideas by coding. The job roles which come under the computer science field are software engineer, hardware engineer, system analyst, and software architect. Hence without one field, the other cannot sustain.
How to choose a programming language for developing a project?
We came across the concept of computing programming, its uses, and different programming languages and fields using programming for their enhancement. But one big question which always roams in everyone's mind is which programming language should we select for a particular project?
To answer this question, first, you need to gather some information about the project you will develop. The information includes:
After the above survey and gathering the information, the project team members should choose a language to program. Can take the following suggestions to select the language.
While working on android applications, use Java, flutter, or Kotlin.
While designing a project on web development, use object-oriented languages like Python, Java, and C++.
If you work on machine learning and data science projects, use either python or R languages. The R language supports statistical analysis and its visualization in a better way.
The above given are the only suggestions. If you are comfortable with other languages, which suit your project, go with them.
How to learn to program?
To start with programming, first choose any basic language like C or C++ to understand the programming concepts, the syntax of the language, and basic things like knowing about the datatypes, operators, conditional statements, etc.
The best way to learn to program in less time is through self-practice itself. Then start mastering algorithms and the data structurespresent in that language. While learning the algorithms and data structures, take help from websites, books, and youtube videos to visualize the concepts better. You can practice them in online sites and compilers, or you can even participate in competitive programming available on various websites.
After you understand and learn the programming language, the next step is creating small projects by applying the knowledge gained. If you can only partially develop a project, then at least try to design small parts like creating a web page, building a calculator app, etc. The project building boosts your confidence, and at the same time, you know how to apply the learned programming language in real-time applications.
Then you can try complex projects and deep dive into emerging technologies like Machine Learning, Artificial Intelligence, Deep learning, Cloud Computing, Mobile Development, Web Development, etc. The more you explore, learn and practice, the more you gain and become perfect.
The computer Programming field covers the various fields of computer science we discussed. Programming is a developing and demanding career shortly. The only thing is to keep updated with the emerging technologies and skills to stand strong in programming.
