What is a Hello World application in software development?

A “Hello World” program is a software program that prints out the phrase “Hello, world!” on a display device. It is typically used to introduce novice programmers to a programming language or system. The phrase itself is derived from an example program in the seminal 1978 book “The C Programming Language.” While the specific wording of the phrase varies depending on the programming language, the imports of a Hello World program remain the same: to provide a simple example that can be used to learn how to develop cross-platform applications. In recent years, Hello World programs have been used to introduce everything from mobile app development to quantum computing. As such, it remains an important part of the software development process.
