This is the usp of C++, it is a set of languages which can be combined as needed depending upon problem requirements (aka Multi-Paradigm). I personally always start with a subset and only add features as needed. Two old books which i found useful in thinking about how to use C++ are; Scientific and Engineering C++ by Barton and Nackman. Multi-paradigm design for C++ by James Coplien. I have not as yet found any equivalents for "Modern C++".
