The constants 1 and 0 are sometimes used to represent the boolean values True and False in programming languages without a boolean type, such as older versions of C.

A "Hello, World!" program is generally a simple computer program which 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.
C# ( / ˌsiː ˈʃɑːrp / see SHARP) [b] is a general-purpose high-level programming language supporting multiple paradigms. C# encompasses static typing, [16] : 4 strong typing, lexically scoped, imperative, declarative, functional, generic, [16] : 22 object-oriented ( class -based), and component-oriented programming disciplines.
BETA (programming language) BETA is a pure object-oriented language originating within the "Scandinavian School" in object-orientation where the first object-oriented language Simula was developed. [1] Among its notable features, it introduced nested classes, and unified classes with procedures into so called patterns.
