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.
In C and C++ short, long, and long long types are required to be at least 16, 32, and 64 bits wide, respectively, but can be more. The int type is required to be at least as wide as short and at most as wide as long , and is typically the width of the word size on the processor of the machine (i.e. on a 32-bit machine it is often 32 bits wide ...
A small piece of code in most general-purpose programming languages, this program is used to illustrate a language's basic syntax. Such program is often the first written by a student of a new programming language, [1] but such a program can also be used as a sanity check to ensure that the computer software intended to compile or run source ...
BASIC-E and early versions of CBASIC compiled source code into an intermediate p-code file, which was then executed by a separate run-time interpreter program. CBASIC could execute in a minimum of 24 KB of memory. Line numbers in the program source were optional, unless needed as a label for a program jump.

Its main focus is to provide a simple and comprehensive environment for middle/high school students to learn the basics of computer programming. [3] Basic-256 started as a simple version of BASIC: the code editor, text output window and graphics display window are all visible in the same screen. [4]
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 ]
Dartmouth BASIC is the original version of the BASIC programming language.It was designed by two professors at Dartmouth College, John G. Kemeny and Thomas E. Kurtz.With the underlying Dartmouth Time-Sharing System (DTSS), it offered an interactive programming environment to all undergraduates as well as the larger university community.
