Introduction to C
What is C?
C is a high-level and general-purpose programming language known for its efficiency and control over system resources. Created in the early 1970s, C provides a foundation for understanding modern programming, as it balances powerful low-level access with a simpler syntax than assembly language. Its emphasis on procedural programming and direct memory manipulation makes it a crucial tool in systems programming.
History and Evolution of C
C was developed at Bell Labs in 1972 by Dennis Ritchie as an evolution of the B programming language. Originally designed to support the UNIX operating system, C quickly spread beyond systems programming due to its performance and portability. Key versions, including ANSI C (standardized in 1989), established C as a foundational language influencing C++, C#, and other languages. Today, C continues to be used in operating systems, embedded systems, and critical applications where efficiency is paramount.
Key Features of C
C’s power lies in its portability and efficiency. It offers low-level access to memory through pointers, minimal runtime support, and fast execution speeds, making it ideal for performance-critical applications. Additionally, C’s simplicity allows it to be easily compiled across various hardware platforms, ensuring portability and making it foundational in systems programming.
