C and C++ is very complicated, I recently had to choose between C 
and C++, but I ended up choosing D instead. the reasons why are.
1. to many baskets not enough eggs.
2. Community designed complexity.

* To many baskets not enough eggs
C was designed to be a systems level programming language, it 
became a general purpose language because of community and 
industry effort, C++ was not designed to be anything it is an 
extension on C it was designed to be C plus extra features, as 
C++ became designed they want there cake and to eat it to, 
meaning that they want every good feature from many other popular 
languages like Haskell, or Python or whatever, however the 
difference between what D has done and C++ is doing that D was 
for the most part designed to Read fast Write fast and Run Fast, 
its on the home page, C++ is designed to be fast, and every other 
feature that C++ tries to add is just a bonus if they can even 
get it to work, for example I cant image C++ with a GC, however 
they talk about adding usability features, and it sure sounds 
like that would be a feature that would help their target 
audience, the designers talk about adding features to help 
scientists but its just talk unless they actually do it, and a GC 
would help, but they are not willing to make sacrifices to make a 
general purpose language, D is a general purpose language, it 
sacrifices Speed when it needs to when you want to just test an 
idea, but you can also make it as fast as C or C++. the design 
has clean edges even if its very broad, while C++ is also very 
broad but it has very rough edges.

* Community Designed complexity
When I tried to learn C++ the part that made me the most confused 
was the community, C style code tends to be faster than C++ style 
code, at least by my metrics and the metrics I have seen, so I 
want to use C to make faster programs, but I like many of the C++ 
libraries and some of the nice features, however when I go to 
learn C++ so much code is in C++ style as a beginner I really 
didnt want to decipher it all, so I just wanted to use C instead 
but then I find out about this awesome C++ library and the cycle 
continues, though this issue was self inflicted, all I had to do 
to fix the issue was to not care about how fast my code is, but 
that is the whole purpose of using C and C++, typically use that 
your code is fast. so why use C++ for ease of use, for me it was 
supposed to be for speed. so again like what I mentioned above 
its meant to be for speed but the code people write is because 
its "Correct" code, because that code according to someone is 
easier, which tends to be slower.

the community the language design in some ways.
