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.

Summary

From this chapter, we learned that we can not only alter program flow with function calls but also execute or omit program statements through the use of conditional statements. The if()… else… statement has a much wider variety of forms and uses. The switch()… statement operates on a single value, comparing it to the desired set of possible constant values and executing the pathway that matches the constant value. if()… else… statements can be chained into longer sequences to mimic the switch()… statement and to provide a richer set of conditions than possible with switch()…. Also, if()… else… statements can be nested in one or both clauses to either make the purpose of that branch clear or the condition for each pathway less complex.

In these conditional statements, execution remains straightforward, from top to bottom, where only specific parts of the statement are executed. In the next chapter, we'll...
