By: Navule Pavan Kumar Rao

Overview of this book

A new language on the block, V comes with a promising set of features such as fast compilation and interoperability with other programming languages. This is the first book on the V programming language, packed with concise information and a walkthrough of all the features you need to know to get started with the language. The book begins by covering the fundamentals to help you learn about the basic features of V and the suite of built-in libraries available within the V ecosystem. You'll become familiar with primitive data types, declaring variables, arrays, and maps. In addition to basic programming, you'll develop a solid understanding of the building blocks of programming, including functions, structs, and modules in the V programming language. As you advance through the chapters, you'll learn how to implement concurrency in V Programming, and finally learn how to write test cases for functions. This book takes you through an end-to-end project that will guide you to build fast and maintainable RESTful microservices by leveraging the power of V and its built-in libraries. By the end of this V programming book, you'll be well-versed with the V programming language and be able to start writing your own programs and applications.

Chapter 3: Variables, Constants, and Code Comments

In the previous chapter, we learned how to install V on various operating systems. Now, it's time for us to learn about the basic concepts in V. This chapter will cover the absolute basics to get started in V, including defining and working with variables, constants, and code comments.

Variables are the foundational concepts of any programming language, and programmers will encounter them almost all the time when they code. Therefore, it is essential to know about the details of variables. Similarly, we will also learn about constants that offer reusability and consistency during programming software applications. Constants hold a value that never changes for the entire lifetime of the application.

Finally, we will gain an understanding of how to make comments in the code. Code comments are an essential part of software development, and they help fellow programmers to read and understand the functionality of the logic...
