Are there any useful/basic classes provided by gcc ?

[Long Fei]

Hi, I am a neophyte of gcc.

I wonder if there are any useful/basic classes (like the class that does all
the string operations, etc.) provided by gcc. Just like JDK, which provides
very powerful API classes. (and microsoft visuall C++ though I don't like
MFC very much.)

If yes, would you please tell me where I can get the documentation ?

I found it really painful to code from the very fundamental classes. If
there are classes provided, I can just new an instance and save a lot of
time.

Thank you in advance.
