Overview of this book

There’s a lot more to C than knowing the language syntax. The industry looks for developers with a rigorous, scientific understanding of the principles and practices. Extreme C will teach you to use C’s advanced low-level power to write effective, efficient systems. This intensive, practical guide will help you become an expert C programmer. Building on your existing C knowledge, you will master preprocessor directives, macros, conditional compilation, pointers, and much more. You will gain new insight into algorithm design, functions, and structures. You will discover how C helps you squeeze maximum performance out of critical, resource-constrained applications. C still plays a critical role in 21st-century programming, remaining the core language for precision engineering, aviations, space research, and more. This book shows how C works with Unix, how to implement OO principles in C, and fully covers multi-processing. In Extreme C, Amini encourages you to think, question, apply, and experiment for yourself. The book is essential for anybody who wants to take their C to the next level.

Compiler

As we discussed in the previous sections, the compiler accepts the translation unit prepared by the preprocessor and generates the corresponding assembly instructions. When multiple C sources are compiled into their equivalent assembly code, the existing tools in the platform, such as the assembler and the linker, manage the rest by making relocatable object files out of the generated assembly code and finally linking them together (and possibly with other object files) to form a library or an executable file.

As an example, we spoke about as and ld as two examples among the many available tools in Unix for C development. These tools are mainly used to create platform-compatible object files. These tools exist necessarily outside of gcc or any other compiler. By existing outside of any compiler, we actually mean that they are not developed as a part of gcc (we have chosen gcc as an example) and they should be available on any platform even without having gcc installed....
