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.

Integration with Java

Java programs are compiled by a Java compiler into Java bytecode. Java bytecode is analogous to the object file format specified in the Application Binary Interface (ABI). Files containing Java bytecode cannot be executed like ordinary executable files, and they need a special environment to be run.

Java bytecode can only be run within a Java Virtual Machine (JVM). The JVM is itself a process that simulates a working environment for the Java bytecode. It is usually written in C or C++ and has the power to load and use the C standard library and the functionalities exposed in that layer.

The Java programming language is not the only language that can be compiled into Java bytecode. Scala, Kotlin, and Groovy are among programming languages that can be compiled to Java bytecode hence they can be run within a JVM. They are usually called JVM languages.

In this section, we are going to load our already built stack library into a Java program...
