The second line asks the compiler to make a new type, which can be a floating position kind "of some type" with at least 5 digits of precision.
Languages that offer containers considered heterogenous only deliver containers of aspects that all present a regular interface. By way of example, Java collections offer containers of (references to) Objects and you utilize the (widespread) Item interface to find the actual type of a component. The C++ normal library offers homogeneous containers since those are the simplest to use from the overwhelming majority of instances, presents the very best compile-time mistake information, and imposes no unneeded operate-time overheads. If you want a heterogeneous container in C++, determine a standard interface for all The weather and come up with a container of People. Such as: course Io_obj /* ... */ ; // the interface needed to take part in item I/O vector vio; // if you'd like to regulate the ideas immediately vector< Take care of > v2; // In order for you a "good pointer" to take care of the objects You should not fall to the bottom volume of implementation element Except You should: vector memory; // almost never desired A good indicator that you've got "long gone far too lower stage" is that your code receives affected by casts. Making use of an Any class, which include Boost::Any, is usually an alternate in some programs: vector v; Why are the typical containers so gradual?
