Do you know how to use initializer lists?

Bitesize Modern C++: std::initializer_list

by Glennan Carnie

From the article:

An aggregate type in C++ is a type that can be initialised with a brace-enclosed list of initialisers. C++ contains three basic aggregate types, inherited from C:

• arrays
• structures
• unions

Since one of the design goals of C++ was to emulate the behaviour of built-in types it seems reasonable that you should be able to initialise user-defined aggregate types (containers, etc.) in the same way...
