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 11 – Working with Arrays

  1. An array definition has a data type, a base name, and a size (or a number of elements).
  2. A constant length array is one whose size can be determined at compile time – its size is a literal number, a #define symbol, a constant expression (such as 13-3), or an enumeration constant.
  3. A variable-length array is one whose size is determined at runtime by the value of a variable, the result of a variable expression, or the result of a function call.
  4. You can initialize a constant-length array when it is defined. You cannot initialize a VLA when it is defined.
  5. VLAs enable function parameters to receive arrays of any size so long as the size is also given as a parameter to the function.
