Languages that offer containers deemed heterogenous simply provide containers of features that all supply a standard interface. Such as, Java collections give containers of (references to) Objects and you employ the (typical) Item interface to find out the actual form of an element. The C++ common library supplies homogeneous containers because those are the simplest to utilize within the overwhelming majority of scenarios, provides the best compile-time mistake message, and imposes no unwanted run-time overheads. If you want a heterogeneous container in C++, define a typical interface for all The weather and create a container of Those people. For example: course Io_obj /* ... */ ; // the interface needed to take part in item I/O vector vio; // if you need to handle the tips directly vector< Take care of > v2; // If you would like a "sensible pointer" to take care of the objects Will not fall to the bottom volume of implementation element unless you have to: vector memory; // almost never required A very good indication that you've got "absent far too low degree" is that your code gets affected by casts. Making use of an Any class, such as Strengthen::Any, might be an alternate in certain packages: vector v; Why are definitely the regular containers so sluggish?

Observe that there's no have to look for self-assignment in a duplicate-constructor. This is due to the copy constructor is barely referred to as when new objects are being created, and there is no method to assign a newly designed object to itself in a method that calls to repeat constructor.
