I spend some time examining boost:: libraries architecture and was interested with the following fact:
I have that template class that uses a policy for it\'s output and another template argument to determine the type for it\'s data members. Furthermore the constructor takes pointers to base classes wh
I\'ve got (probably) a simple question. When do I have to declare a function used in a template? The following code prints out (using gcc >=4.1):

I\'ve recently returned to C++ development after a hiatus, and have a question regarding implementation of the State Design Pattern. I\'m using the vanilla pattern, exactly as
In a header file, I have forward declared two members of a namespace: namespace Foo { struct Odp typedef std::vector<Odp> ODPVEC;
I understand that wherever possible we shall use forward declarations instead of includes to speed up the compilation.
I have a header file that has some forward declarations but when I include the header file in the implementation file it gets included after the includes for the previous forward declarations and this
