A hello world program that conforms to the C standard is also a valid C++ hello word program. The following is Bjarne Stroustrup's version of the Hello world program that uses the C++ Standard Library stream facility to write a message to standard output: [61] [62] [note 2]
The C++ standard library is a collection of utilities that are shipped with C++ for use by any C++ programmer. It includes input and output, multi-threading, time, regular expressions, algorithms for common tasks, and less common ones (find, for_each, swap, etc.) and lists, maps and hash maps (and the equivalent for sets) and a class called vector that is a resizable array.
The empty computer file is the minimal program in Simula, measured by the size of the source code. It consists of one thing only; a dummy statement. However, the minimal program is more conveniently represented as an empty block: Begin End; It begins executing and immediately terminates. The language lacks any return value from the program.
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". A quine is a fixed point of an execution ...
C++ classes. A class in C++ is a user-defined type or data structure declared with any of the keywords class, struct or union (the first two are collectively referred to as non-union classes) that has data and functions (also called member variables and member functions) as its members whose access is governed by the three access specifiers ...
Eigen (C++ library) Eigen is a high-level C++ library of template headers for linear algebra, matrix and vector operations, geometrical transformations, numerical solvers and related algorithms. Eigen is open-source software licensed under the Mozilla Public License 2.0 since version 3.1.1. Earlier versions were licensed under the GNU Lesser ...
Turbo C. Turbo C is a discontinued integrated development environment (IDE) and compiler for the C programming language from Borland. First introduced in 1987, it was noted for its integrated development environment, small size, fast compile speed, comprehensive manuals and low price. In May 1990, Borland replaced Turbo C with Turbo C++.
Harbour (programming language) Harbour is a computer programming language, primarily used to create database/business programs. It is a modernised, open source and cross-platform version of the older Clipper system, which in turn developed from the dBase database market of the 1980s and 1990s. Harbour code uses the same databases and can be ...
