Overview of C Programming Language
C is a general-purpose programming language that provides low-level access to memory, straightforward syntax, and a variety of data structures. Its design promotes structured programming and allows for the development of efficient software. The fourth edition of this book presents a comprehensive overview of C, emphasizing both the language's capabilities and its practical applications.
Historical Context
- Origins: C was developed in the early 1970s at Bell Labs by Dennis Ritchie as an evolution of the B programming language. It was designed to implement the Unix operating system, which has significantly influenced modern operating systems.
- Standardization: The American National Standards Institute (ANSI) standardized C in 1989, leading to the ANSI C standard (often referred to as C89 or C90). Subsequent updates, such as C99 and C11, have added new features and enhancements to the language.
Structure of the Book
The C Programming Language 4th Edition is structured to facilitate learning through a clear and logical progression. Each chapter builds on the previous one, introducing new concepts while reinforcing earlier material.
