<< c <<":"<< count[i]<< endl; } } return 0;} 总结 stl vector是C++程序员必备的容器之一，具有动态扩展、快速访问和尾部添加/删除元素等优点。在使用stl vector时，需要注意初始化、添加/删除元素、访问元素等操作。通过案例分析，我们可以看到stl vector的实际应用场景和使用方法。
说明:vector是C++中一个的容器类,它用于存放类型相同的元素,利用成员函数及相关函数可以方便的对元素进行增加或删除,排序或逆序等等。一个 vector 的容量(capacity)永远大于或等于其大小(size),一旦容量等于大小,便是满载,下次再有新增元素,整个 vector 容器就得重新申请一块更大的连续容量空间(一般是两倍原来容量大小...
Vectors are not ordered in C++. Vector elements are placed in adjacent storage and can be easily accessed and traversed across using iterators. In vectors, data is inserted at the end when we use push_back() function . Inserting an element at the end of a vector takes differential time, a...
#include<stdio.h>#include<stdlib.h>#include<typeinfo>#include<vector>using namespace std;intmain(){vector<int>vec1;vec1.resize(10);//调增容器大小和元素数量(调用默认构造函数)vector<int>vec2={1,2,3};//使用初始化列表来初始化vec2.reserve(10);//仅调整容器大小,但是元素个数不变vector<int...
使用vector容器,即避免不了进行查找,所以今天就罗列一些stl的find算法应用于vector中。 find() Returns an iterator to the first element in the range [first,last) that compares equal to val. If no such element is found, the function returns last. ...

You can visualize speaker embeddings using a trained d-vector. Note that you have to structure speakers' directories in the same way as for preprocessing. e.g. python visualize.py LibriSpeech/dev-clean -w wav2mel.pt -c dvector.pt -o tsne.jpg The following plot is the dimension reduction...
如需詳細資訊,請參閱vector::insert (STL/CLR)。 insert(ContainerRandomAccessIterator<TValue>, IEnumerable) 將列舉程式所指定的序列插入容器。 C# publicvoidinsert(Microsoft.VisualC.StlClr.Generic.ContainerRandomAccessIterator<TValue> _Where_iter, System.Collections.IEnumerable _Right); ...
命名空间: Microsoft.VisualC.StlClr 程序集: Microsoft.VisualC.STLCLR.dll 分配并初始化新的 VectorEnumeratorBase<TValue> 对象。 C# 复制 public VectorEnumeratorBase (Microsoft.VisualC.StlClr.IVector<TValue> _Cont, int _First); 参数 _Cont IVector<TValue> 要进行循环访问的容器。 _First In...
