For example, the following statement creates a <a href="cppvector_details.html">vector</a> of integers: <pre>vector<int> v;</pre> Containers can hold standard objects (like the <strong>int</strong> in the above example) as well as custom objects, as long as the objects in the container meet a few requirements: <ul> <li>The object must have a default constructor,</li> <li>an accessible destructor, and</li> <li>an accessible assignment operator.</li> </ul> When describing the functions associated with these various containers, this website defines the word <strong>TYPE</strong> to be the object type that the container holds. For example, in the above statement, <strong>TYPE</strong> would be <strong>int</strong>. </body></html>⌨️ 快捷键说明
