Changes to C++98 Containers

C++11 brings three main changes to the container class methods.

First, the addition of rvalue references makes it possible to provide move semantics (Chapter 18, “Visiting with the New C++ Standard”) for containers. Accordingly, the STL now provides move constructors and move assignment operators for containers. These methods take an rvalue reference argument.

Second, the addition of the initializer_list template class (Chapter 18) has led to constructors and assignment operators that accept an initializer_list argument. This makes code like the following possible:

vector<int> vi{100, 99, 97, 98};vi = {96, 99, 94, 95, 102};

Third, the addition of variadic templates and function parameter packs (Chapter 18) makes emplacement ...
