C for C# Programmers is a practical, clear, and friendly guide for developers who already know C# and now want to learn the C programming language with confidence. Designed as part of the CodeSwitch series, this book focuses on the mindset shift needed when moving from a managed, object-oriented world to a low-level, memory-centric one. You will learn not only how C works, but why it works the way it does.
Unlike many traditional C textbooks, this book does not start from zero. It speaks your language as a C# developer. Familiar concepts are mapped directly to their C equivalents, while the differences are explored in depth, including memory management, pointers, manual allocation, stack and heap behaviour, compilation, linking, and the absence of a runtime or automatic garbage collection.
You will discover how to translate high-level patterns into efficient C code, how to avoid common pitfalls, and how to work safely and effectively on embedded systems, microcontrollers, and performance-critical applications. Examples are written side by side in C and C#, making comparisons easy to follow. The early "Mindshift" chapter highlights the essential conceptual changes you need to make when moving from C# to C, helping you think like a C programmer from the very beginning.
Inside this book you will learn:
How C's procedural model differs from the C# object model
How variables, types, arrays, structs, and functions map between the two languages
How memory is managed manually through pointers and the stack
How to compile, link, debug, and structure multi-file C projects
How to write safe, robust C code in embedded and systems contexts
How to recognise and avoid C's most common errors and traps
Whether you want to build embedded firmware, understand legacy systems, or deepen your knowledge of how software works at a low level, this book will guide you step by step. It is ideal for self-learners, professional developers, students, and anyone who wants to expand their skills beyond the managed environment of C#.
C for C# Programmers gives you the tools, insight, and confidence to write real, working C programs and to understand the language that underpins much of modern computing.
