Overview of this book

Software engineering is a set of techniques, including programming, within the computer science discipline associated with the development of software products. This practical guide to software engineering will enable aspiring and new developers to satisfy their curiosity about the industry and become ready to learn more about the basics before beginning to explore programming languages, along with helping junior and upcoming developers to effectively apply their knowledge in the field. The book begins by providing you with a comprehensive introduction to software engineering, helping you gain a clear, holistic understanding of its various sub-fields. As you advance, you’ll get to grips with the fundamentals of software engineering, such as flow control, data structures and algorithms. The book also introduces you to C# and guides you in writing your first program. The concluding chapters will cover case studies, including people working in the industry in different engineering roles, as well as interview tips and tricks and coding best practices. By the end of this programming book, you'll have gained practical knowledge of the implementation and associated methodologies in programming that will have you up and running and productive in no time.

Introduction to the selection sort algorithm

In the previous section, we saw that the steps to complete array operations can vary based on the position of the data. We sometimes arrange and organize data in such a way that it is more readable and faster to find what we’re looking for, and computers can benefit from this too. A data structure that contains sorted data, such as a numerical sequence stored in an array, takes fewer steps to complete an operation such as reading or insertion. Sorting algorithms also take several steps to complete the sorting process. We will explore the selection sort algorithm, which is a common sorting algorithm that finds the smallest element in a data structure and moves it to the front. Let’s dive in by exploring an example of an array that contains four integers:

We can easily organize this sequence in our heads, but writing an algorithm to do this will...
