Hello, world! Programs are usually written to make the text “Hello, world!” appear on a computer screen. This is also a basic sanity check for an installation of a new programming language. The first Hello World program appeared in chapter 1.1 of the first edition of Kernighan & Ritchie’s original book about C, ‘The C Programming Language’, in 1978. This is considered to be the first ever “Hello World!” program.
This document is a result of a committee formed at Indian Hill to establish a common set of coding standards and recommendations for the Indian Hill community. The scope of this work is the coding style, not the functional organization of programs. The standards in this document are not specific to ESS programming only.
As we begin the study of C++ and object oriented programming, a few comments are in order to help you get started. Since the field of object oriented programming is probably new to you, you will find that there is a significant amount of new terminology for you to grasp. This is true of any new endeavor and you should be warned not to be intimidated by all of the new concepts.
A constructor is a special method that is created when the object is created or defined. This particular method holds the same name as that of the object and it initializes the instance of the object whenever that object is created. The constructor also usually holds the initialization of the different declared member variables of its object.
