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.

Accessing array elements

Each element of an array is accessed via its base name and an index into the array. An index is also known as a subscript. Each element is accessed using the following form:

arrayName[ index ]

Here, index is a value between 0 and the (array size minus 1). We can access any element of an array using this form. Just as with defining an array, the index may be a literal value, a variable, the result of a function call, or the result of an expression, as follows:

float anArray[10] = {2.0};
int   counter = 9;
float aFloat  = 0.0; 
aFloat = anArray[ 9 ];             // Access last element.
aFloat = anArray[ counter ];       // Access last element 
                             ...
