代码(待更新): class Vector Private length Private data() Sub Class_Initialize() length= End Sub '插入元素' public Function Add (byval x) length=length+ ) data(length-)=x End Function '快速展示' public Function display() dim i dim s s=s & cstr(data(i)) & "…
1. 包含一个头文件: 1 #include <vector> 2. 申明及初始化: std::vector<int> first; // empty vector of ints std::vector<,); // four ints with value 100 std::vector<int> third (second.begin(),second.end()); // iterating through second std::vector<in…

Implement an iterator to flatten a 2d vector. For example,Given 2d vector = [ [1,2], [3], [4,5,6] ] By calling next repeatedly until hasNext returns false, the order of elements returned by next should be: [1,2,3,4,5,6]. Hint: How many variables do y…
在项目中需要在一定条件满足时,保存一些数据到数据库中,并可根据条件查询.考虑到WinCC6.2以后采用的就是SQL Server2005数据库,所以直接利用该数据库即可,通过SQL Server Management Studio(SSMS)可以创建自己的数据库,并安要求创建好表. 一.数据库连接 在SQL Server Management Studio(SSMS)中创建名为evcp的数据库,再创建名为evcp的表,然后根据需要创建Columns,在本项目中创建了norder(流水号).pil…
List接口的一些列实现中,最常用最重要的就是这三个:ArrayList.Vector.LinkedList.这里我就基于JDK1.7来看一下源码. public class ArrayList<E> extends AbstractList<E> implements List<E>, RandomAccess, Cloneable, java.io.Serializable public class Vector<E> extends AbstractL…
