C++ Story Repository

Prologue

The C++ Story pulls together presentations on C++ syntax and semantics, and example code, to present a tutorial on the C++ programming language. Also provided are exercises at the end of most chapters. The story consists of 12 chapters on: basics of C++ syntax and semantics, classes, class relationships and their use to build compound objects, templates, template specialization, and template metaprogramming. The concluding chapters cover standard libraries and other interesting topics.

Chap 1. - Models

Chapter 1 focuses on C++ language syntax and semantics before classes. It discusses all the things C++ added to C, describes its type system, points to basic code examples to review, and ends with a discussion of C++ models for compilation, program execution, and use of memory. Finally, there are a set of exercises for you to test your skills. The exercises start out with simple requests with discussion about how you satisfy them. Later exercises require some design on your part.

Chap 2. - Language Survey

This page provides brief descriptions of the major C++ language features and a few of its many libraries. It also describes a few libraries that I built for CSE687 - Object Oriented Design class work.

Chap 3. - Data

C++ types, type qualifiers and type structures are presented first. That's followed by type system casts, new standard types (C++17), data initialization, and smart pointers. The last part covers building data structures with the STL library components.

Chap 4. - Operations

Chapter 4 focuses on manipulating data. First it covers type coercions, copy construction, copy assignment, functions, function pointers, methods, method pointers, functors, and lambdas. Next comes callable objects, passing function and method parameters and side effects, return values and return value optimization. The chapter concludes with STL algorithms and testing.

Chap 5. - Classes

Topics are basic classes, class methods with examples, building value types, and resource allocation. Next is class anatomy, a survey of a lot of moving parts, followed by compiler-generated methods. The chapter ends with examples of classes from the C++ Repositories.

Chap 6. - Class Relationships

The chapter starts with an overview of the four fundamental relationships: inheritance, composition, aggregation, and using. That is followed by object layout, and an important compound object layout demonstration. The chapter closes with inheritance, run-time polymorphism, and virtual dispatching, followed by two non-trivial examples.

Chap 7. - Templates

Template functions, and overloading start the chapter. Then type categories, type transformations, and substitution failure is not an error (SFINAE). The first part ends with examples. The second part focuses on template classes, class template parameters, and template class specialization. Chapter 7 ends with two practical examples.

Chap 8. - Template Metaprogramming

C++ template semantics require compiler computations as part of the build process. There is a functional language that directs these compile-time computations to build things like variadic functions and classes. This chapter begins with a simple example using that functional language. It continues with variadic functions, variadic classes, and both standard and custom compile-time entities and type traits. The chapter closes with compile-time selections and two examples.

Chap 9. - Libraries

Chapter 9 provides a quick summary of both standard and custom libraries via a table of links.

Chap 10. - Stream Libraries

Stream Libraries starts with a quick overview of the std::iostream library, continuing with streams formatting examples, and examples of stream operations for: standard file streams, filebuf, read-write, and string streams.

Chap 11. - STL Libraries

Starting with a quick overview of containers and their iterators, the chapter continues with containers, then Algorithms, and closes with examples.

Chap 12. - Other Interesting Topics

Chapter provides links for: C++ Patterns, declarative programming, templates, and a few other "odds and ends".

Code Contents:

This repository holds narrative and code examples used in the C++ story. Note:
All of the code here has been implemented using Visual Studio, so each item below has a visual studio project. Every one of them need the C++17 language option set. That should already be part of the project settings, but if something fails to compile, please check the language option.
  1. Chapter1-C++ Models
    • Chapter1-Structure Demo with two components and an executive. One of the components provides an interface and object factory.
