Gagniuc P. An Introduction to Programming Languages. Simultaneous Learning 2023

Textbook in DJVU format

After a short introduction on the history of programming languages, this book provides step-by-step examples that are mirrored in seven programming languages, including C#, C++, Java, JavaScript, PERL, PHP, Python, Ruby, VB, and VBA. This mirrored approach for each of the examples represents the main feature of the book with the goal of gaining a better understanding of the advantages and disadvantages of programming and scripting languages. This approach also allows readers to learn the mechanics of short implementations and the algorithms involved, no matter what technology and programs are used in the future. Based on the growing need for programmers to be proficient across languages, the book is designed in such a way that no prior training or exposure to the programming languages is needed by readers.
Graphical illustrations are used for technical details about the computation examples to aid in an in-depth understanding of their inner workings. Moreover, the book contains original material that has been class-tested by the author and numerous cases are examined. Readers will also benefit from the inclusion of: (1) Historical and philosophical perspectives on the past, present and future of computer languages. (2) A total of 448 additional files are freely available online, from which a total of 44 files are poster presentations (i.e. PowerPoint and PDF files). (3) A total of 404 code examples reflected in nine computer languages, namely: C#, C++, Java, JavaScript, PERL, PHP, Python, Ruby and VB
