C and C++ Under the Hood: 2nd Edition - Softcover

Inhaltsangabe

This second edition of the the highly acclaimed first edition provides the reader with an invaluable insight into C and C++ in particular and programming languages in general. Although the title of the book, C and C++ Under the Hood, suggests that the book has a narrow scope, in fact, just the opposite is true: It is an introduction to assembly language, programming language design, object-oriented programming, assemblers, compilers, interpreters, linkers, computer architecture, and system programming. You will learn what happens at the machine level corresponding to the features, constructs, operations, and extensions of the C and C++ programming languages. For example, you will learn

• what an object in memory looks like and how its functions are called and its data accessed
• why dynamic local variables have no default values but global variables do
• how virtual functions are implemented
• what happens during a call by reference
• what is the difference between static functions and ordinary functions
• some interesting parameter-passing extensions (pass by value-result, pass by name)
• what happens when a recursive function is executed
• what startup code is and what is its function
• how two separately-compiled modules are linked together
• what is in object and executable files
• how to write an assembler and a linker
• how to write a machine language interpreter

The book is accompanied by a free download which includes an easy-to-use but powerful assembler, linker, interpreter, and debugger program for the Windows, Mac OS X, Linux, and Raspberry Pi systems. Included in the book are a number of well-defined system programming projects that support the material covered. This second edition incorporates a number of improvements:

• The text includes a new chapter on the microlevel accompanied by supporting software so readers can write and experiment with their own microcode. In addition, the software package contains a second new chapter in pdf format on virtual memory.
• The software package now includes slides for the textbook.
• The directions and shell programs for the projects in the system programming chapter have been improved.
• The instruction set has been substantially expanded and improved.
• The text now uses the more standard gcc assembly language format and directives. The software supports both the gcc format and the format and directives used in the first edition.
