Overview of this book

Learning how to code has many advantages, and gaining the right programming skills can have a massive impact on what you can do with your current skill set and the way you advance in your career. This book will be your guide to learning computer programming easily, helping you overcome the difficulties in understanding the major constructs in any mainstream programming language. Computer Programming for Absolute Beginners starts by taking you through the building blocks of any programming language with thorough explanations and relevant examples in pseudocode. You'll understand the relationship between computer programs and programming languages and how code is executed on the computer. The book then focuses on the different types of applications that you can create with your programming knowledge. You'll delve into programming constructs, learning all about statements, operators, variables, and data types. As you advance, you'll see how to control the flow of your programs using control structures and reuse your code using functions. Finally, you'll explore best practices that will help you write code like a pro. By the end of this book, you'll be prepared to learn any programming language and take control of your career by adding coding to your skill set.

Mobile applications

When we talk about a mobile application, we usually mean a program that is designed to run on a mobile device, such as a smartphone. These devices have some special characteristics that we need to consider when writing an application. First, their screen is smaller than a computer monitor. The screen can also be rotated in landscape or portrait orientation. We will also use the touchscreen of the device for input.

The mobile application might also use other features of the device, such as the GPS, sending text messages, or sensing the movement of the device using its accelerometer. These are things we usually can't do if an application runs on a normal computer.

A mobile application can be connected, but it does not have to be. Being connected means that it can communicate with another computer, maybe using the client-server techniques we discussed earlier.

When writing a mobile application, the platform the application will run on is very important...
