I am a C++ newbie and I am struggling on the temporaries topic. I don't find anywhere a clear list of all cases in which the compiler will create a temporary. Actually, a few days ago I had in mind...

I have been coding in C++ for past few years. But there is one question that I have not been able to figure out. I want to ask, are all temporaries in C++, rvalues? If no, can anyone provide me an...

This may be impossible, but I was wondering if it was possible to keep a temporary from ever lasting past its original expression. I have a chain of objects which point to parent objects, and a mem...

I'm doing something similar to this item Correct BOOST_FOREACH usage? However, my returned list is wrapped in a boost::shared_ptr. If I do not assign the list to a variable before the BOOST_FOREAC...

Consider the following code : void ListenerImpl::attach(boost::shared_ptr<ISubscriber> subscriber) { boost::unique_lock<boost::mutex>(mtx); subscribers.push_back(subscriber); } void...

I'm told that, in C++03, temporaries are implicitly non-modifiable. However, the following compiles for me on GCC 4.3.4 (in C++03 mode): cout << static_cast<stringstream&>(strings...

Section 12.2.5 in C++03 says "A temporary bound to a reference member in a constructor’s ctor-initializer (12.6.2) persists until the constructor exits" So I tried following program #include<i...

I've got a C++ data-structure that is a required "scratchpad" for other computations. It's not long-lived, and it's not frequently used so not performance critical. However, it includes a random nu...

For this program #include <iostream> using std::cout; struct C { C() { cout << "Default C called!\n"; } C(const C &rhs) { cout << "CC called!\n"; } }; const C f() { cou...
