Detailed Description

template<class T>
class std::initializer_list< T >

C++ standard support for "initializer_list".

This creates a temporary array in C++11 list-initialization and then references it. An initializer_list instance is automatically constructed when a braced-init-list is used to list-initialize an object, where the corresponding constructor accepts an initializer_list parameter.

Using an initializer_list argument is done through a standard C++ iterator loop:

void f(initializer_list<int> list) {
    for (auto x : list)
        cout << *x << endl;
}

where the iterator type is simply const T*. That code could also be written in a more traditional and more verbose way:

void f(initializer_list<int> list) {
    for (const int* x = list.begin(); x != list.end(); ++x)
        cout << *x << endl;
}
