Hi!
A great feature - I think - is, when languages, running in a virtualized way like C# and Java show errors during you're working on the source. Most often IDEs like Eclipse or NetBeans or VisualStudio have the feature to specify errors immediately.
Is there anything like this for C/C++? Just for coding... I'm currently searching for a way to gain the same coding experience with good old C :).
Eclipse has C and C++ support with the CDT project. I've never personally used it but I would assume it has everything you want.
You can program in C++ in Visual Studio and it will give you the same intellisense an error highlighting features you would expect from it's other languages.
You don't see these kind of tools often for old languages such as C++. It's really hard to create a compiler/parser for C++.

The C++ standard does not specify a machine-readable definition of the C++ grammar, and the question whether a given sequence of characters is legal C++ is undecidable. Building tools reliably processing C++ code (including compilers) is extremely hard.

This is always present in my mind when think about C++. It is C++ which make things difficult. Why not code in another language which is more elegant and easier to parse. Why struggle with Herculean labours against C++ when it's crippled by not being easily machine-processable. We're programmers! We write programs to do things for us! If C++ itself isn't amenable to being manipulated by programs, then why allow it to reside in your toolbox?
Netbeans and Sun Studio have C/C++ support (Sun Studio seems to have more advanced debugging features).
