C How to Program, 9e (Paul Deitel, Harvey M. Deitel) (z-library.sk, 1lib.sk, z-lib.sk)

【One-Line Pitch】 A comprehensive, hands-on C programming textbook that takes you from your first "Hello, World" to building your own compiler, with a strong emphasis on modern secure coding practices and real-world applications—ideal for beginners and self-taught programmers who want a solid, practical foundation in C. 【Book Arc】 - **Opening (~0%–10%)**: Introduces the fundamentals of computing, the C language's history and significance, and sets up the development environment. It covers the full program-development cycle (edit, preprocess, compile, link, load, execute) and provides detailed, platform-specific guides for running C code on Windows, macOS, Linux, and even in a Docker container with GCC. - **Early (~10%–23%)**: Dives into the first actual C programs. You'll learn the basic structure of a C program, core syntax, and the role of the linker and standard library. This section also includes practical, step-by-step walkthroughs for setting up and running projects in IDEs like Xcode, making the transition from theory to practice seamless. - **Early-Middle (~23%–32%)**: Focuses on the building blocks of logic and control flow. It introduces key concepts like escape sequences, the `if` statement, and the crucial distinction between definitions (which allocate memory) and executable statements. The importance of pseudocode as a planning tool is also established here. - **Middle (~32%–48%)**: Deepens your understanding of program control with a detailed look at iteration. The book uses a class-average problem to teach sentinel-controlled loops, emphasizing the importance of handling edge cases like division by zero. This section also introduces secure C programming concepts, such as avoiding arithmetic overflow and using safer function variants like `scanf_s`. - **Late (~48%–100%)**: Moves into advanced topics and data structures. This includes formatted input/output with `printf` and `scanf` (field widths, precision, flags), and then structures, unions, bit manipulation, and enumerations. The book culminates in a major project: building a simple compiler that translates a high-level language into machine code for the simulated computer you built earlier, followed by an introduction to sorting algorithms and Big O notation. 【Key Takeaways】 - **C is foundational and still dominant** (Early): Understanding C gives you insight into how operating systems (Linux, Windows, Android) and other languages work. It's not just a historical language; it's a practical skill for systems programming and performance-critical applications. - **The development cycle is a multi-phase process** (Early): A C program isn't just compiled; it goes through preprocessing, compilation, linking, and loading. Knowing this pipeline helps you debug issues like linker errors, which occur when the compiler can't find a library function. - **Pseudocode is your blueprint** (Middle): Before writing a single line of C, you should plan your algorithm in pseudocode. This informal, English-like language helps you "think out" the logic and order of operations, making the final translation to C much easier and less error-prone. - **Control flow requires careful planning** (Middle): Sentinel-controlled loops are essential for processing data when you don't know the input size in advance. Always test for edge cases, like division by zero, to prevent fatal runtime errors and crashes. - **Secure coding is a core concern** (Middle): Modern C programming requires awareness of vulnerabilities. This includes avoiding arithmetic overflow (which can lead to undefined behavior) and using safer library functions like `scanf_s` to prevent buffer overflows and format string attacks. - **Data structures are built from `struct`s** (Late): The book shows how to aggregate related data into custom types using `structs` and `typedefs`. These are the foundation for building dynamic data structures like linked lists, stacks, queues, and binary trees that can grow and shrink at runtime. - **Formatted I/O is a powerful tool** (Late): Mastering `printf` and `scanf` with their various conversion specifiers, field widths, and flags gives you precise control over how data is displayed and read, which is crucial for creating professional and user-friendly applications. 【Reading Tips】 - **Skim the platform-specific setup guides** (Early): If you already have a working C environment, you can skim the detailed steps for Visual Studio, Xcode, and Docker. However, if you're a beginner, pick one platform and follow its guide carefully to ensure your setup is correct. - **Deep-read the "Secure C Programming" sections**: These are not just side notes; they are critical for writing robust, production-quality code. Pay close attention to the rationale behind using safer functions and avoiding common pitfalls like overflow. - **Don't skip the pseudocode examples**: They are the key to understanding the problem-solving process. Try writing your own pseudocode for the exercises before looking at the C solutions. This will train you to think algorithmically. - **Treat the compiler project as a capstone**: The "Building Your Own Compiler" case study is a major undertaking. Don't rush it. It ties together many concepts from the book and is an excellent way to solidify your understanding of how high-level code translates to machine instructions. - **Use the Self-Check exercises**: These are integrated throughout the text and provide immediate feedback. They are a quick and effective way to verify you've understood a concept before moving on. 【Coverage Limits】 This guide is based on a sample of the book's content, focusing on the introductory chapters and the table of contents. It does not cover the detailed content of later chapters on pointers, file processing, or the specifics of the sorting algorithms and Big O analysis, which are mentioned but not excerpted in detail.
