C Language: C is a general-purpose, procedural, imperative computer programming language. It was developed by M. Dennis Ritchie at Bell Telephone Laboratories developed by the Unix Operating system.
This C tutorial is mainly designed for software programmers, students with a need to understand the C programming language starting from scratch. It will give you enough understanding of the programming language.
Before proceeding with the C language tutorial, readers/users must have a basic knowledge of understanding C programming terminology. If you have any basic knowledge regarding any programming knowledge it will help us to understand the C programming language easily.
It was a general-purpose, procedural, imperative computer programming language. It was developed by M. Dennis Ritchie at Bell Telephone Laboratories with the Unix Operating system. While it was also known as the basic language for all other programming languages.
C has become famous for various reasons like:
C programming language was developed to overcome the difficulties found in other programming languages such as BCPL, BASIC, B, etc.,

While the introduction of K & R, the language which is a new edition of this was published in 1978. And also several features have been included in the language. During the late 190s, it was started to use for a wide variety of mainframe computers.
While ANSI C standards emerged in the early 1980s, this book was split into two titles i.e. it was originally called Programming in C. While the title that covered ANSI C was called Programming in ANSI C. Besides it was done because it took several years for the compiler vendors to release their compilers and for them to become famous. Actually, It was designed for programming UNIX operating system.
