  2. C file input/output - Wikipedia

    en.wikipedia.org/wiki/C_file_input/output

    The C programming language provides many standard library functions for file input and output.These functions make up the bulk of the C standard library header <stdio.h>. [1] The functionality descends from a "portable I/O package" written by Mike Lesk at Bell Labs in the early 1970s, [2] and officially became part of the Unix operating system in Version 7.

  3. Quine (computing) - Wikipedia

    en.wikipedia.org/wiki/Quine_(computing)

    A quine's output is exactly the same as its source code. A quine is a computer program that takes no input and produces a copy of its own source code as its only output. The standard terms for these programs in the computability theory and computer science literature are "self-replicating programs", "self-reproducing programs", and "self-copying programs".

  4. C (programming language) - Wikipedia

    en.wikipedia.org/wiki/C_(programming_language)

    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 ...

  5. "Hello, World!" program - Wikipedia

    en.wikipedia.org/wiki/"Hello,_World!"_program

    A "Hello, World!" program is generally a simple computer program that emits (or displays) to the screen (often the console) a message similar to "Hello, World!" while ignoring any user input. A small piece of code in most general-purpose programming languages, this program is used to illustrate a language's basic syntax.

  7. Huffman coding - Wikipedia

    en.wikipedia.org/wiki/Huffman_coding

    The process of finding or using such a code is Huffman coding, an algorithm developed by David A. Huffman while he was a Sc.D. student at MIT, and published in the 1952 paper "A Method for the Construction of Minimum-Redundancy Codes". [1] The output from Huffman's algorithm can be viewed as a variable-length code table for encoding a source ...

  8. Compiler - Wikipedia

    en.wikipedia.org/wiki/Compiler

    A compiler is a computer program that translates a program written in a high-level language (HLL), such as C, into an equivalent assembly language program [2]. ^ Sun, Chengnian; Le, Vu; Zhang, Qirun; Su, Zhendong (2016). "Toward understanding compiler bugs in GCC and LLVM".

  9. conio.h - Wikipedia

    en.wikipedia.org/wiki/Conio.h

    For the profanity, see coño on Wiktionary. conio.h is a C header file used mostly by MS-DOS compilers to provide console input/output. [1] It is not part of the C standard library or ISO C, nor is it defined by POSIX. This header declares several useful library functions for performing "istream input and output" from a program.
