As of now, we know that vectors are used to store elements. They can handle dynamic data well; it is very easy to initialize data in vector by using methods available in C++. They also provide resizing of the data because they provide and come up with better flexibility to handle the dy...
If, we want to initialize a vector with initial elements, we can use following syntax, vector<data_type> vetor_name{elements}; C++ Vector Iterator To access/iterate elements of a vector, we need an iterator for vector like containers. We can use following syntax to declare a vector iterato...
The second constructor is a default copy constructor that can be used to create a new vector that is a copy of the given vectorc. 翻译:第二个构造器是一个默认的复制构造函数,它可以用来创建一个新的向量,它是给定向量c的副本。 The third constructor creates a vector with space fornumobjects. If...

The 3D vector is a vector of vectors, like the 3D array. It stores elements in the three dimensions. It can be declared and assign values the same as a 3D matrix. The 3D Vector is a dynamic which has the capability to resize itself automatically when an element is to be inserted or ...
