The book "Mathematical and Algorithmic Foundations of Object-Oriented Programming", created by the team of authors, is a fascinating and deep dive into the world of programming, where mathematics and algorithms become the basis for understanding the object-oriented approach. This work not only teaches, but also inspires, opening up new horizons for readers in software development. From the first pages, the book captures attention, offering the reader a unique look at how mathematical concepts and algorithmic thinking form the basis for creating effective and reliable programs. Unlike many other textbooks, the emphasis here is not only on the syntax of programming languages, but also on a deep understanding of the principles behind object-oriented programming (OOP). The reader will learn how abstraction, encapsulation, inheritance, and polymorphism work in the context of real-world problems, making the material particularly relevant for those who aspire to become not just an executor, but a real architect of software solutions. This book will be of interest to both novice programmers and those who already have experience in developing . Students of IT-specialties, graduate students, as well as professionals who want to deepen their knowledge, will find a lot of useful information in it. In addition, it will be useful to teachers who are looking for quality materials for their courses. The book is suitable for readers aged 16 to 50 who are interested in programming, mathematics and algorithms. The themes that are raised in the book are diverse and relevant. The authors consider not only theoretical aspects, but also practical applications of mathematical methods in programming. Readers will be able to learn how to use algorithms to solve real-world problems, as well as how to properly structure the code so that it is clear and easy to maintain. This work highlights the importance of logical thinking and analytical approach in software development, making it particularly valuable in an era when technology is rapidly evolving. The style of the authors is characterized by accessibility and clarity of presentation, which allows even complex concepts to be explained in simple and understandable language. This makes the book not only a tutorial, but also a fascinating read for anyone who wants to expand their horizons in programming. The team of authors includes experienced programmers and teachers, which adds additional value to the material - each of them shares his unique experience and views on the subject. If you are looking for programming books that will help you master the basics of OOP and mathematical algorithms, then “Mathematical and algorithmic foundations of object-oriented programming” will be a real find for you. It will not only give you the necessary knowledge, but also inspire you to create your own projects, equipping you with the tools necessary for a successful career in IT. This book is not just a textbook, but a whole world in which you immerse yourself to become a master of programming. If you want to understand how modern technologies work and learn how to apply mathematical and algorithmic principles in your practice, then do not miss the opportunity to get acquainted with this work.
