Hello World
Free AppAbout Hello World
A "Hello, world!" program is a computer program that outputs "Hello, World!" (or some variant thereof) on a display device. Because it is typically one of the simplest programs possible in most programming languages, it is by tradition often used to illustrate to beginners the most basic syntax of a programming language. It is also used to verify that a language or system is operating correctly.
A "Hello, world!" program has become the traditional first program that many people learn. In general, it is simple enough so that people who have no experience with computer programming can easily understand it, especially with the guidance of a teacher or a written guide. Using this simple program as a basis, computer science principles or elements of a specific programming language can be explained to novice programmers. Experienced programmers learning new languages can also gain a lot of information about a given language's syntax and structure from a "Hello, world!" program.
In addition, "Hello, world!" can be a useful sanity test to make sure that a language's compiler, development environment, and run-time environment are correctly installed. Configuring a complete programming toolchain from scratch to the point where even trivial programs can be compiled and run can involve substantial amounts of work. For this reason, a simple program is used first when testing a new tool chain.

Like the developer wrote: "Hello World" software/app is traditionally the first program one will make. --- Another version that I always make has an input field/box.... So the program/app will say "Hello World !" then it will ask "...is anybody out there ?", and I can answer whatever I want. ___ Thanks for making me smile ___ Have a good day ;-)
