C (pronounced / ˈsiː / – 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. It has found lasting use in operating systems code (especially in kernels [ 7 ...
Don't repeat yourself. " Don't repeat yourself " (DRY) is a principle of software development aimed at reducing repetition of information which is likely to change, replacing it with abstractions that are less likely to change, or using data normalization which avoids redundancy in the first place. The DRY principle is stated as "Every piece of ...
The C Programming Language (sometimes termed K&R, after its authors' initials) is a computer programming book written by Brian Kernighan and Dennis Ritchie, the latter of whom originally designed and implemented the C programming language, as well as co-designed the Unix operating system with which development of the language was closely intertwined.
Examples of the general concept include: "Avoid doing what you would blame others for doing." – Thales [12] (c. 624 – c. 546 BCE) "What you do not want to happen to you, do not do it yourself either." – Sextus the Pythagorean. [13] The oldest extant reference to Sextus is by Origen in the third century of the common era. [14]
The C standard library or libc is the standard library for the C programming language, as specified in the ISO C standard. [ 1 ] Starting from the original ANSI C standard, it was developed at the same time as the C library POSIX specification, which is a superset of it. [ 2 ][ 3 ] Since ANSI C was adopted by the International Organization for ...
The C language specification includes the typedef s size_t and ptrdiff_t to represent memory-related quantities. Their size is defined according to the target processor's arithmetic capabilities, not the memory capabilities, such as available address space. Both of these types are defined in the <stddef.h> header (cstddef in C++).

In the C programming language, operations can be performed on a bit level using bitwise operators. Bitwise operations are contrasted by byte-level operations which characterize the bitwise operators' logical counterparts, the AND, OR, NOT operators. Instead of performing on individual bits, byte-level operators perform on strings of eight bits ...
