Smart pointers and polymorphism

Cleaning up an STL list/vector of pointers

What is the shortest chunk of C++ you can come up with to safely clean up a vector or list of pointers? (assuming you have to call delete on the pointers?) list<Foo*> foo_list; I'd rather not use Boost or wrap my pointers with smart pointers.

Casting - Why Should I do it for Upcasting

stackoverflow.com - 2013-04-29 18:49:38 - Similar - Report/Block

I have been reading some other threads on this site, and they mention how dynamic_cast and static_cast are both safe for upcasting. Why are these even required for upcasting? For example, if class B is derived from A, then A * ptr = new B (); still works, and behaves like an object of type A. (I am also from a Java background where conver...

Calling a non-virtual function in derived class using a base class pointer

As noted in this answer high reliance on dynamic_cast is often an indication your design has gone wrong. What I'd like to know is how can I call a custom function in a derived class, for which there is no same-name function in the base class, but do so using a base class pointer and perhaps without dynamic_cast if in fact there is a bett...
