Learn C Programming - Second Edition

By: Jeff Szuhay

Overview of this book

The foundation for many modern programming languages such as C++, C#, JavaScript, and Go, C is widely used as a system programming language as well as for embedded systems and high-performance computing. With this book, you'll be able to get up to speed with C in no time. The book takes you through basic programming concepts and shows you how to implement them in the C programming language. Throughout the book, you’ll create and run programs that demonstrate essential C concepts, such as program structure with functions, control structures such as loops and conditional statements, and complex data structures. As you make progress, you’ll get to grips with in-code documentation, testing, and validation methods. This new edition expands upon the use of enumerations, arrays, and additional C features, and provides two working programs based on the code used in the book. What's more, this book uses the method of intentional failure, where you'll develop a working program and then purposely break it to see what happens, thereby learning how to recognize possible mistakes when they happen. By the end of this C programming book, you’ll have developed basic programming skills in C that can be easily applied to other programming languages and have gained a solid foundation for you to build on as a programmer.

Chapter 16 – Creating and Using More Complex Structures

  1. The compositions are as follows:
    1. Card is a simple structure of intrinsic and enumerated types.
    2. Hand is a structure that consists of an array of pointers.
    3. Deck is a structure that consists of an array of structures, an array of pointers, and intrinsic types.
  2. Stepwise refinement. Each step in the process takes a working program and adds features to it until the desired program is complete.
  3. Magic numbers are literal values that have special significance that represent real-world meaning. While magic numbers are a natural part of things we represent in our programs, we should strive to give added meaning to those numbers through the use of constant variables, enumerated constants, and preprocessor symbols.
  4. In one case, enumerated constants for Face and Suit that are related to each other use the e- prefix. In the other case, enumerated constants for array sizes are unrelated and use the k- prefix.
