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.

Chapter 8: Understanding Functions

There are a number of useful concepts that we, as programmers, always should follow. One is to write code that is easy to read and understand. Another is to avoid duplicating code. When you start out your career as a programmer, you will find yourself copying and pasting code and just changing some small things here and there. This is a bad habit as it nullifies the first concept of code that is easy to read because reading more or less the same lines over and over is tedious and it is hard to spot the tiny differences.

A better solution is to package code that we want to reuse several times into a function. A function is a way for us to give a name to a block of code and then, with this name, the code block can be called over and over every time we want it to execute.

In this chapter, you will learn the following:

  • Deciding what goes into a function
  • Writing a function
  • Returning values from a function
  • Passing arguments to...
