C++ is not quite a superset of C, though most reasonable C code is valid C++. However, C++ includes a lot of facilities that make programming easier. They're easy to abuse, sure, but in most cases they help make things clearer and simpler.
Boost is almost a second standard library (it is one reference source used in the standards process), and it demonstrates a lot of what's cool and awful about C++. Boost invented a lot of the smart pointer classes that are now standard and save a lot of boilerplate that makes memory management in C annoying. Boost has things like Asio, which lets you write portable synchronous/asynchronous network code. On the other hand, it has Spirit, which is a massive abuse of operator overloading which is at once both impossibly complex and nifty/convenient.
Linus's opinion is worth noting, but he's hardly the best source.
