I am a beginner programmer. I have c++ primer plus by stephen prata the 2nd edition (1995). A lot of the content is old, for example, the header files seem to be slightly different (#include <limits.h> instead of the current #include <climits> ...). Should I still use this book? (later on I might not be able to spot the differences) But I prefer reading a book to an ebook.
19 years is a long time in terms of C++ (or probably any) language development. There have been at least two major revisions to the C++ standard since then. I'd suggest looking for a more recent book.
