"1, C" refers to a specific programming language known as C, which is widely used for system and application software development. The "1" indicates the first version of this language, which was developed in the early 1970s by Dennis Ritchie at Bell Labs. It is known for its efficiency and control over system resources. The language is foundational for many modern programming languages, including C++ and Java. Its syntax is relatively simple, making it accessible for beginners while still powerful enough for advanced programming tasks. C is often used in operating systems, embedded systems, and high-performance applications.
