PART V: Appendices 572Appendix A: C++ Reserved Keywords 575Appendix B: Standard Headers 577Appendix C: The Development Environment 579Bibliography 601Index 603Learn C++, Patterns, and Qt 4 Cross-Platform Development
Master C++ and design patterns together, using the world's leading open source framework for cross-platform development: Qt 4.
An Introduction to Design Patterns in C++ with Qt 4 is a complete tutorial and reference that assumes no previous knowledge of C, C++, objects, or patterns. You'll walk through every core concept, one step at a time, learning through an extensive collection of Qt 4.1-tested examples and exercises.
By the time you're done, you'll be creating multithreaded GUI applications that access databases and manipulate XML files--applications that run on platforms including Windows, Linux, Unix, and Mac OS X. Best of all, you'll be writing code that's efficient, reusable, and elegant.
