I'm slightly afraid to learn C++ after being told so many horror stories. But for the low low price of free? Count me in.
Now C is a different matter.
Still, if you look at the Chromium code, or the Doom 3 BFG Edition code, it's really neat and readable.
If you want to learn a next generation language right now then you should look at Rust. It seriously has the ability to replace C++ in the long term. C++ will be remembered as the third dino besides Fortran and Cobol.
