1、array(C++11) array 是固定长度的数组,定义时就指定长度,一旦定义长度不能更改(不能扩容)。 template<typename_Tp,std::size_t_Nm>structarray{typedef_Tpvalue_type;typedefvalue_type*pointer;typedefconstvalue_type*const_pointer;typedefvalue_type&reference;typedefconstvalue_type&const_reference;typedefvalue...
Reference: http://beginnersbook.com/2013/12/difference-between-arraylist-and-vector-in-java/ JAVA COLLECTIONS ArrayListandVectorboth use Array as a data structure internally. However there are few differences in the way they store and process the data. In this post we will discuss the difference ...
Both Vector and ArrayList use growable array data structure. The iterator and listIterator returned by these classes (Vector and ArrayList) are fail-fast. They both are ordered collection classes as they maintain the elements insertion order. Vector & ArrayList both allows duplicate and null values....
Vector , ArrayList classes are implemented using dynamically resizable array providing fast random access and fast list traversal very much like using an ordinary array . ArrayList support dynamic arrays that can grow as needed that is ArrayList can be dynamically increased or decreased in size . Rea...
Even though both the arraylists and vectors are very similar to dynamic arrays that can grow in size, they have some important differences. The main difference between arraylists and vectors is that the vectors are synchronized whereas arraylists are unsynchronized. Therefore using arraylists in mul...
boost::array与std::vector使用与性能 大家都希望可以像操作STL容器一样的去操作数组,C++可没有提供这个东西,有时候你会选择使用vector来替代,不过这毕竟不是个好的办法,毕竟vector模拟动态数组比较稳妥,而用它去替代一个普通的数组,开销毕竟太大了。而恰好,boost::array就为你提供了这个功能。boost::array的定义...

Note:Source's vector class[Clarify]is geometric andverydifferent fromthe Standard Template Library's, which is a type ofarray. The STL-style vector has been renamedCUtlVectorin Source. Declaration Vector vecMyVector = Vector(1,20,5);
