Why error?
Hi, I want to know which clause in the C++ standard guides the "Ambiguous base class conversion" related error that this code throws. Actually, there are two issues: 1. There are two 'A' subobjects in B3 and hence 'A' is an ambiguous base class 2. 'A' is both a public and a private indirect base class in 'B3'... 2 Aug 2010 01:41

Compiling C++ Templates as opposed to Preprocessing them.
Hi, Can readers of this forum advise on whether it would be fruitful to consider compiling C++ templates to IR instead of preprocessing them? Consider the following snippet: template<class T> void foo(const T &t) { ... 13 Aug 2010 10:17

value_type of an output iterator
Hi, The value_type of an output iterator is defined to be void, and there seems to be a good reason for this. How should I modify the following code without having to make value_type a template parameter of make_pairs? Thanks, Shaun #include <iostream> #include <iterator> using namespace std; struct... 3 Aug 2010 18:02

why are missing return statements from non-void functions not a compilation error
> One of them, C4715, is "not all control paths return a value". Sure enough, the function in question has a return type of int, and there are various embedded returns but no final return at the end, a control path that it can get to. Warning! I once tried to fix all the functions that where suppose to ret... 30 Jul 2010 08:34
