You can use any part of C++ without having to use the rest of it. For example, you don't have to write your own std::allocator to use std::vector, nor do you have to use exceptions.
You can use which bits of C++ that you want - that's its great strength, permitting low-level behaviour whilst supporting high level abstractions (and as simple or as complex as you like).
