My dad has had a book for a while, published under Pearson, by the name of "How to program in C and C++, Second Edition" (title in Spanish: Cómo programar en C y C++, Segunda Edición), which after some investigation was made by H.M and P.J Deitel, so I want to know if the contents of said book are still relevant today (I have heard that C++ has had some major updates, I don't know about C though), so I can use it to learn a thing or two.
Found a website in spanish which has the book in PDF format, so like: https://elsolucionario.net/como-programar-en-cc-deitel-deitel-2ed/
