What is C Programming Language? Basics, Introduction, History
Let’s learn about C language in this basic C language tutorial: It is said that ‘C’ is god’s programming language. It can be said that C is a basis for programming. If you know ‘C’, you can easily gain knowledge of other programming languages that use the ‘C’ concept Read: What is c & f It is essential to have a background in memory mechanics computer memory as it is an important aspect when dealing with the C programming language.IEEE-10 Best Top Programming Languages of 2018In this C programming tutorial you will learn the basics of C language like:

History of the C language
Contents
The base or father of programming languages is ‘ALGOL.’ It was first introduced in 1960. ‘ALGOL’ has been widely used in European countries. ‘ALGOL’ introduced the concept of structured programming to the developer community. In 1967, a new computer programming language was announced called ‘BCPL’, which stands for Basic Associative Programming Language. BCPL was designed and developed by Martin Richards, especially for writing system software. This is the age of programming languages. Only after three years, in 1970, a new programming language named ‘B’ was introduced by Ken Thompson which had many features of ‘BCPL.’ This programming language was created using the UNIX operating system at AT&T and Bell Laboratories. Both ‘BCPL’ and ‘B’ are system programming languages.

It is created from the programming languages ’ALGOL’, ‘BCPL’ and ‘B’. The ‘C’ programming language contains all the features of these languages and many other additional concepts that make it unique from other languages. ‘C’ is a powerful programming language closely associated with the UNIX operating system. Even most UNIX operating systems are coded with ‘C’. Initially ‘C’ programming was limited to the UNIX operating system, but as it began to spread around the world, it became commercial and many compilers were released for cross-platform systems. Today ‘C’ runs on many different operating systems and hardware platforms. As it began to develop, various versions of the language were released. Sometimes it becomes difficult for developers to update to the latest version because the system is running under older versions. To ensure that the ‘C’ language would remain the standard, the American National Standards Institute (ANSI) defined a commercial standard for the ‘C’ language in 1989. It was subsequently approved by the Foundation. The International Standards Organization (ISO) approved it in 1990. The ‘C’ programming language is also known as ‘ANSI C’.
History of languages like C++/Java evolved from ‘C’. These languages are widely used in different technologies. Thus, ‘C’ forms the basis for many other languages currently in use.

Why learn C Language?
As we studied earlier, ‘C’ is the base language for many programming languages. So learning the main language as ‘C’ will play an important role while studying other programming languages. It shares concepts like data types, operators, control statements, and many more. ‘C’ can be widely used in different applications. It is a simple language and offers faster execution. There are many jobs available to a ‘C’ developer in the current market. ‘C’ is a structured programming language where the program is divided into various modules. Each module can be written separately and together form a single ‘C’ program. This structure makes it easy to test, maintain, and debug processes. ‘C’ contains 32 keywords, various data types and a set of powerful built-in functions that make programming very efficient.

We can add our features and functions to the library. We can access and use these functions anytime we want in our program. This feature makes it simple while working with complex programs. There are many compilers available in the market that can be used to execute programs written in this language. . This feature is essential if we want to use or execute the code on another computer.
How does the C programming language work?
C is a compiled language. A compiler is a special tool that compiles a program and converts it into a machine-readable object file. After the compilation, the linker will combine the different object files and create a single executable to run the program. The following diagram shows the execution of program ‘C’
Nowadays many different compilers are available online and you can use any of them. The functionality will never be different and most compilers will provide the necessary features to execute both ‘C’ and ‘C++’ programs. Top Q&A
- Clang compiler
- MinGW Compiler (Minimalist GNU for Windows)
- Portable ‘C’ compiler
- SUPER TURBO
Summary
- ‘C’ was developed by Dennis Ritchie in 1972.
- It is a powerful language.
- It is a low-level programming language close to machine language
- It is widely used in the field of software development.
- It is a structure and procedure oriented language.
- It has full support of different operating systems and hardware platforms.
- Many compilers are available to execute programs written in ‘C’.
- The compiler compiles the source file and generates the object file.
- The linker links all the object files together and creates an executable.
- It is highly portable.
