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.
Generally, for C/C++ the include directive is used to include a header file, but can include any file. Although relatively uncommon, it is sometimes used to include a body file such as a .c file. The include directive can support encapsulation and reuse. Different parts of a system can be segregated into logical groupings yet rely on one ...
C instructions can be a single statement or a block in the form of: { statements} while (condition) instructions: do instructions while (condition); for («type» i = first; i <= last; i++) instructions — Objective-C: for (type item in set) instructions: C++ (STL) «std::»for_each(start, end, function) Since C++11: for (type item : set ...

C language example This example in C uses two tables, the first (CT1) is a simple linear search one-dimensional lookup table – to obtain an index by matching the input (x), and the second, associated table (CT1p), is a table of addresses of labels to jump to.
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 ]
The File namespace is a namespace consisting of administration pages in which all of Wikipedia's media content resides. On Wikipedia, all media filenames begin with the prefix File:, including data files for images, video clips, or audio clips, including document length clips; or MIDI files (a small file of computer music instructions).
In Ruby, interpreter directives are referred to as pragmas and are specified by top-of-file comments that follow a key: value notation. For example, coding: UTF-8 indicates that the file is encoded via the UTF-8 character encoding. In C#, compiler directives are called pre-processing directives. There are a number of different compiler ...
