Techopedia Explains Hello World

When programmers are first introduced to a programming language, they are usually given an initial sample of the language in the form of a very short and simple program. The usual output of this sample program is the character string “Hello World” displayed on the screen. As such, the program itself is also known as Hello World. In some tutorials, the succeeding text will then explain some of the code used for the Hello World program to give the aspiring programmer a foretaste of things to come.
