Module 9: Advanced C Features and Modern Standards

Overview

This module explores advanced features introduced in modern C standards (C99, C11, C17, and C23) as well as contemporary development practices. You’ll learn about variable-length arrays, designated initializers, static assertions, thread-local storage, and many other features that make modern C more powerful and expressive. The module also covers modern development practices including DevOps integration, containerized development, and cloud-native C programming.

Learning Objectives

By the end of this module, you will be able to: - Understand and apply C99 features including variable-length arrays and designated initializers - Utilize C11 features such as static assertions and thread-local storage - Implement C17/C23 features including typeof operators and binary literals - Apply modern C development practices and tools - Understand contemporary C ecosystem including WebAssembly and cloud-native development - Work with advanced preprocessor features - Implement generic programming techniques using modern C features - Apply best practices for modern C development

Chapters

  1. C99 Features - Variable-length arrays, designated initializers, compound literals, restrict keyword, inline functions
  2. C11 Features - Static assertions, anonymous structures/unions, thread-local storage, bounds-checking functions
  3. C17 and C23 Features - typeof operators, binary literals, enhanced preprocessor directives, attributes
  4. Modern C Development Practices - DevOps integration, containerized development, WebAssembly, cloud-native C
  5. Advanced Preprocessor - Macro definitions, conditional compilation, pragma directives, token manipulation
