containers

Context: .NET 3.5, VS2008. I'm not sure about the title of this question, so feel free to comment about the title, too :-) Here's the scenario: I have several classes, say Foo and Bar, all of them implement the following interface: public interface IStartable { void Start(); void Stop(); } And now I'd like to have a container class, which gets an IEnumerable<IStartable> as an argument in its constructor. This class, in turn, should also implement the IStartable interface: public class StartableGroup : IStartable // this is the container class { private readonly IEnumerable<IStartable>

I have a number of unrelated types that all support the same operations through overloaded free functions (ad hoc polymorphism): struct A {}; void use(int x) { std::cout << "int = " << x << std::endl; } void use(const std::string& x) { std::cout << "string = " << x << std::endl; } void use(const A&) { std::cout << "class A" << std::endl; } As the title of the question implies, I want to store instances of those types in an heterogeneous container so that I can use() them no matter what concrete type they are. The container must have value semantics (ie. an assignment between two containers

Let's say I need to retrieve the median from a sequence of 1000000 random numeric values. If using anything but std::list , I have no (built-in) way to sort sequence for median calculation. If using std::list , I can't randomly access values to retrieve middle (median) of sorted sequence. Is it better to implement sorting myself and go with e.g. std::vector , or is it better to use std::list and use std::list::iterator to for-loop-walk to the median value? The latter seems less overheadish, but also feels more ugly.. Or are there more and better alternatives for me? Any random-access container

What are the general use cases for the C++ standard library containers ? bitset deque list map multimap multiset priority_queue queue set stack vector For example, a map is generally better for a paired search.

1 - I'm reading the documentation and I'm slightly confused with the wording. It says: ClusterIP : Exposes the service on a cluster-internal IP. Choosing this value makes the service only reachable from within the cluster. This is the default ServiceType NodePort : Exposes the service on each Node’s IP at a static port (the NodePort). A ClusterIP service, to which the NodePort service will route, is automatically created. You’ll be able to contact the NodePort service, from outside the cluster, by requesting <NodeIP>:<NodePort> . LoadBalancer : Exposes the service externally using a cloud

I have a bunch of inline-block elements over several lines which I'd like to center horizontally. The inline-block elements all have the same fixed size, but I'd like the centering to be able to handle page resizing and adding or removing elements. I've stripped down the html/css and removed the attempt at centering for clarity. It's at http://jsfiddle.net/fe25H/1/ If you resize the results window so that the third inline-block element drops down, the container fills the width and we get this: -----------------BODY------------------ | | ||-------------CONTAINER-------------|| ||-INLINEBLOCK--
