basics of C programming explained

C programming

C is a widely-used general-purpose programming language that is easy to learn and use. It is a machine-independent structured programming language that is widely used to create a variety of applications, operating systems such as Windows, and other complicated programmes such as the Oracle database, Git, Python interpreter, and others.

C is supposed to be the programming language of gods. C can be considered a programming foundation. You can readily understand the knowledge of other programming languages that employ the concept of ‘C’ if you know ‘C.’

It is necessary to have knowledge about computer memory mechanisms. since it is essential while working with the C programming language

The origins of the C programming language

‘ALGOL’ is the foundation or father of all programming languages. In 1960, it was initially introduced. In many European countries, ‘ALGOL’ was widely utilized. The concept of structured programming was first introduced to the developer community by ‘ALGOL.’ A new computer programming language named ‘BCPL,’ which stands for Basic Combined Programming Language, was announced in 1967. Martin Richards created and built BCPL specifically for writing system software. The era of programming languages had arrived. Three years later, in 1970, Ken Thompson presented a new programming language called ‘B,’ which had many of the characteristics of ‘BCPL.’ At AT&T and Bell Laboratories, this programming language was developed utilizing the UNIX operating system. Both the ‘BCPL’ and the ‘B’ were programming languages for systems.

Dennis Ritchie, a brilliant computer scientist, devised the ‘C’ programming language at Bell Laboratories in 1972. It was built using the programming languages ‘ALGOL,’ ‘BCPL,’ and ‘B.’ All of these properties are present in the ‘C’ programming language, as well as a number of other notions that distinguish it from other languages.

The powerful programming language ‘C’ is closely linked to the UNIX operating system. The majority of the UNIX operating system is written in the C programming language. ‘C’ programming was first exclusive to the UNIX operating system, but as it gained popularity around the world, it became commercial, and various compilers for cross-platform systems were created. C is now available for a wide range of operating systems and hardware platforms. Many distinct versions of the language were released as it developed. Because the systems were running on older versions, it was often difficult for the engineers to keep up with the latest version. In 1989, the American National Standards Institute (ANSI) created a commercial standard for the ‘C’ language to ensure that it would remain standard. It was later recognized by the International Organization for Standardization (ISO) in 1990. ‘ANSI C’ is another name for the ‘C’ programming language.

Where does C come into play? The Most Important Applications

In embedded systems, the ‘C’ programming language is commonly employed.

It’s a programming language that’s used to create system applications.

It’s extensively used for desktop application development.

The majority of Adobe’s programmes are written in the C programming language.

It is used in the development of browsers and addons. The ‘C’ programming language is used to create Google’s Chromium.

It is employed in the creation of databases. MySQL is the most widely used database programme written in C.

It’s employed in the creation of operating systems. The ‘C’ programming language is used to create operating systems such as Apple’s OS X, Microsoft’s Windows, and Symbian. It is used to create operating systems for both mobile phones and desktop computers including gaming PC.

It’s utilised in the creation of compilers.

It’s commonly utilised in Internet of Things (IoT) applications.

Why should you study C?

C is a basic language for numerous programming languages, as we saw earlier. As a result, understanding ‘C’ as the primary language will be useful for learning other programming languages. It uses the same data types, operators, control statements, and other notions. The letter ‘C’ can be used in a wide range of applications. It is a basic language that allows for quicker execution. In today’s industry, there are numerous opportunities for a ‘C’ developer.

‘C’ is a structured programming language that divides a programme into different modules. Each module can be written alone, but when combined, they constitute a single ‘C’ programme. This framework facilitates process testing, maintenance, and debugging.

C has 32 keywords, a variety of data types, and a set of powerful built-in functions that make programming a breeze.

Another property of ‘C’ programming is its ability to self-extend. Various functions from a library are included in a ‘C’ programme. We have the option of adding our own features and functions to the library. In our application, we can access and use these functions whenever we want. This capability makes working with sophisticated code much easier.

There are a number of compilers on the market that may be used to run programmes written in this language.

What is the C Programming Language and How Does It Work?

C is a compiled programming language. A compiler is a tool that compiles a programme and turns it to an object file that can be read by machines. The linker combines different object files after the compilation process and creates a single executable file to run the application.

Various compilers are available online nowadays, and you can use any of them. The functionality will never change, and most compilers will include all of the capabilities needed to run both ‘C’ and ‘C++’ programmes.

The following is a list of popular online compilers:

  • Clang is a compiler for C++.
  • MinGW is a compiler for Windows (Minimalist GNU for Windows)
  • Turbo C is a portable ‘C’ compiler.
