Standard C++ classes

Is there a way that I can look at the source code for the standard C++ classes? When I look in the header files like iostream.h all I see are declarations, but no implementation.

Depends on your compiler.

MSVC++ 6

Check the CRT directory.

There doesn't seem to be a CRT directory, and any CRT files are encrypted

You'll have to update your installation - it's an optional install. The files aren't encrypted.
