In this book I give you my honest views on the good and dark sides of Windows 11. There are more features, issues, hacks and tricks hiding in Windows 11 than most people will ever know. I unveiled some of them in this book.I've been a Windows user for over 20 years, and after further exploring two early builds of Windows 11, at first I had to admit that it looks rather nice, and is better than Windows 10.But I soon discovered there's a lot more than meets the eye. So I strongly advise you read this book first to help you decide if you should install or upgrade your OS to Windows 11.These are some of what you'll learn in this book:The new features and major changes since the Windows 11 insider preview was released.Why Microsoft's system health-check application, and the hardware constraints they plan to include in Windows 11 are shameful, and how they can affect your system and you.Why I suspect the rollout of Windows 11 will be relatively slow, and why it will take quite a long time before lots of people start using it.Apps experiencing troubles with Windows 11 and why Microsoft is unable to find a fix.8 Windows 11 troubles Microsoft is currently investigatingThe Microsoft's policy and how it will affect Windows 11 users when Windows 10 support ends on October 14th, 2025.How to quickly and reliably check if your system can run Windows 11.Two methods to install Windows 11 step by step (for Windows and Linux-based systems with backup and restore options for programs and files).A work around to install Windows 11 on non-supported hardware.How to dual boot your PC with Windows 11 and 10 step by step.And so much more...

C differs from most programming languages in its use of expressions, pointers, and arrays. For those learning C, pointers are the greatest source of confusion. The primary aim of this text is to provide working models of how pointers are used in C as well as an introduction to their use in C++. Most beginners falter on the use of pointers. Many try to avoid pointers completely, but quickly find that pointers are used extensively throughout C programs. Some attain a partial understanding of pointers which, at first, gets them by. However, when faced with complex programming tasks, they find that pointers become a necessity. In most programming languages one learns about pointers only after most other topics have been discussed. Pointers are just one more added feature of the language. In C and in C++, however, pointers are used with every feature. There are pointers to variables, pointers as parameters, pointers as arrays, pointers to structures, and even pointers to pointers. With each feature pointers are used differently. The way pointers work with variables is very different from the way pointers work with arrays. In this text, you learn pointers as you learn each feature of the language. With variables, you learn pointers to variables; with parameters, pointers to parameters; with functions: pointers to functions; with arrays, pointers in arrays; with structures, pointers to structures. In addition, for C++ you will learn pointers to objects, to class members, and derived objects. Such an approach provides an understanding of the many different ways pointers are used throughout the language. The text is arranged in five sections. The first section focuses on the basic structure of the language. Variables, functions, and expressions are carefully examined. The second section deals with arrays. Arrays form an exception in C. Unlike structures they are not data objects. They are completely managed by pointers. The third section describes data structures and file management. The chapter on data structures introduces basic concepts such as linked lists and trees. A special examination is made of recursion and how it operates with lists, trees, and b-trees. The chapters on file management discuss the different types of files with special emphasis on record files b-tree indexes. The fourth section provides an introduction to C++, covering classes and objects, their use with pointers, as well as operator overloading and inheritance. The fifth section covers additional topics greater detail such as the pre-processor and bitwise operations.

GCC 8.0 GNU Compiler Collection Internals documents the internals of the GNU compilers, including how to port them to new targets and some information about how to write front ends for new languages. It corresponds to the compilers (GCC) version 8.0.1. The use of the GNU compilers is documented in a separate manual. See Section "Introduction" in Using the GNU Compiler Collection (GCC).This manual is mainly a reference manual rather than a tutorial. It discusses how to contribute to GCC (see Chapter 1 [Contributing], page 3), the characteristics of the machines supported by GCC as hosts and targets (see Chapter 2 [Portability], page 5), how GCC relates to the ABIs on such systems (see Chapter 3 [Interface], page 7), and the characteristics of the languages for which GCC front ends are written (see Chapter 5 [Languages], page 59). It then describes the GCC source tree structure and build system, some of the interfaces to GCC front ends, and how support for a target system is implemented in GCC.This manual is available online for free at gnu.org. This manual is printed in grayscale.
