How relevant are C/C++ books from 1997?(r/worldnews)
The most recommended book on C is K&R which is from ’88 and still relevant.
C++ books from ’97 are going to be next to worthless. See the recommended books list.
Note that C and C++ are rather different languages and you should decide which one you want to learn before setting out.
