以 vector 为例,必须说明 vector 保存何种对象的类型,通过将类型放在类型放在类模板名称后面的尖括号中来指定类型: vector<int> ivec;//ivec holds objects of type intvector<Sales_item> Sales_vec;//holds Sales_items vector 不是一种数据类型,而只是一个类模板,可用来定义任意多种数据类型。vector 类型的...
The vector<bool> class is a full specialization of the class template vector for elements of type bool. It has an allocator for the underlying type used by the specialization.The vector<bool> reference class is a nested class whose objects can provide references to elements (single bits) ...

std::vector(forTother thanbool) meets the requirements ofContainer,AllocatorAwareContainer(since C++11),SequenceContainer,ContiguousContainer(since C++17)andReversibleContainer. All member functions ofstd::vectorareconstexpr: it is possible to create and usestd::vectorobjects in the evaluation of a con...
1.Construct an empty vector to hold objects of type Widget: vector<Widget> vWidgets; // --- // | // |- Since vector is a container, its member functions // operate on iterators and the container itself so // it can hold objects of any type. 2.Construct...

add(new Float(57.4)); // iterating the vector to print the Objects for (Object O: V) { /* as Vector holds hetrogeneous data objects, thus we have to cast the object to it's type in order to do this we are using getName() function which gets the name of the class of the ...
In this syntax, T represents the data type of the elements in the Vector. For example, the NativeProcessStartupInfo class includes an arguments property. The API reference lists this property as having the type Vector.<String>, meaning that the property is a Vector containing String objects. ...

Mdl = fitcecoc(X,Y) returns a trained ECOC model using the predictors X and the class labels Y. example Mdl = fitcecoc(___,Name,Value) returns an ECOC model with additional options specified by one or more Name,Value pair arguments, using any of the previous syntaxes. For example, spec...
