Welcome to the GDNet C++ Workshop – Ch. 18

For a complete introduction to this workshop, please look here. Workshop Overview This workshop is designed to aid people in their journey to learn beginning C++. This workshop is targeted at highly motivated individuals who are interested in learning C++ or who have attempted to learn C++ in the past, but found that without sufficient support and mentoring they were unable to connect all the pieces of this highly complex but powerful programming language. This is a 'guided' self-teaching C++ workshop. Each student is responsible for taking the time to read the material and learn the information. The community and tutors that arise out of this workshop are here for making the learning process run more smoothly, but are not obligated to baby-sit a person's progress. Because everyone will be working from the same textbook (Teach Yourself C++ in 21 days 5th Ed.), students may find it easier to get answers to the specific questions they might have. There is no minimum age requirement, and there is no previous programming experience required. Additionally, this workshop does not attempt to defend C++ as a language, nor does it attempt to demonstrate that C++ is either more or less useful then other programming languages for any particular purpose. People who intend to start a discussion about the differences between C++ and ANY other languages (except as are relevant to a particular discussion), are encouraged to do so elsewhere. This workshop is for educational, not philosophical discussions. Quizzes & Exercises Each week will have quizzes and exercises posted in the weekly threads. Please try and answer them by yourself. As well, please DO NOT post the answers to Quizzes and Exercises within this thread. Once it becomes acceptable to post the answers to quizzes and exercises, an additional thread will be created each week specifically for the purpose of posting quiz answers. If you try with reasonable effort but are unable to answer the questions or complete the exercises, feel free to post a clarification question here on the thread. Tutors, myself, or others will do the best we can to point you in the right direction for finding the answer.

Chapter 18 – Creating and Using Namespaces

Introduction Greetings everyone! After many months of being offline, the final four weeks of the C++ Workshop are finally being posted. It's unfortunate that it took so long to get these posted, but...no one can say we didnt finish it. It's unfortunate that it took so long, but on the bright side, we've saved the best for last. This, and the next 3 chapters are perhaps the most interesting and advanced subjects in the C++ language. In this chapter we will revisit namespaces. Although we've been using them throughout the workshop, and we had an in-depth discussion in the earlier chapters, this chapter finally reveals the mysteries of the Namespace to all those who've yet to comprehend the intricacies of name clashes and the infamous "multiply defined type" linker errors. After this chapter is complete, the majority of your questions about namespaces should be answered. Outline of the Reading - Chapter 18

1. Getting Started
2. Resolving Functions and Classes by Name
3. Creating a Namespace
4. Using a Namespace
5. The using Keyword
6. The Namespace Alias
7. The Unnamed Namespace
8. The Standard Namespace - std

Good Luck!
