C (pronounced / ˈ s iː / – like the letter c) [6] is a general-purpose programming language. It was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted CPUs.

If you're an absolute beginner who only has basic familiarity with operating a computer, this book will help you learn the most fundamental concepts and practices you need to know to become a successful C programmer.

The syntax of the C programming language is the set of rules governing writing of software in C. It is designed to allow for programs that are extremely terse, have a close relationship with the resulting object code, and yet provide relatively high-level data abstraction.

The C standard library, sometimes referred to as libc, [1] is the standard library for the C programming language, as specified in the ISO C standard. [2] . Starting from the original ANSI C standard, it was developed at the same time as the C POSIX library, which is a superset of it. [3] .

2025年1月8日 · Here’s how it stacks up against C++, Java, C#, Go, Rust, Python, and the newest kid on the block—Carbon. The C programming language has been alive and kicking since 1972, and it still reigns...

Here are some code snippets and explanations I’ve written for some intermediate C concepts that might be useful to you: CS107 reader includes a primer on C along with lots of other useful information related to the language and computer science.

C23, formally ISO/IEC 9899:2024, is the current open standard for the C programming language, which supersedes C17 (standard ISO/IEC 9899:2018). [1] It was started in 2016 informally as C2x, [2] and was published on October 31, 2024. [3] The freely available draft most similar to the one published is document N3220 [4] (see Available texts, below).

ANSI C, ISO C, and Standard C are successive standards for the C programming language published by the American National Standards Institute (ANSI) and ISO/IEC JTC 1/SC 22 /WG 14 of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).
