技术这个东西真是要是不会，全都感觉难的不行不行的，但是要是会了，就会感觉很简单，没有难的技术，只有不会的技术。` class MyComm : public CnComm { public: MyComm() { CnComm(); dInput = -1.0;}bool bLock;void OnReceive(){ i

所谓用邻接矩阵，是用一个二维数组存储，边使用矩阵来构建模型，这使得每一个顶点和其它顶点之间都有边的有无 的 表示的机会。若有边，则他们交点 为1 ，否则为0。当然，如果是一副边有权值的图，交点存储的是他们边的权值。 有1必有回1则为无向图，有1未必有回1则为有向图const int MAX_VERTEX = 3;//数据的数量struct ArrayGraph{ vector<strin

Swapping doubles is easily implemented with three copies, However, although the same logic works to swap larger types, it comes with a significant cost: Now the copies are very expensive. In C++11, if

In C++, there are several different mechanisms for returning from a function. The most straightforward mechanism to use is return-by-value.vectorpartialSum(const vector&arr){    vectorresult(arr.s

double average(double a, double b);//call-by-value;void swap(double &a,double &b);//call-by-reference. in C++11, this is more technically call-by-lvalue-reference.string randomItem(const vector&ar

An lvalue is an expression that identifies a non-temporary object. An rvalue is an expression that identifies a temporary object or is a value (such as a literal constant) not associated with any obje

C++ details(Pointers)A pointer variable is a variable that stores the address where another object resides. It is the fundamental mechanism used in many data structures. For instance, to store a l

The C++ standard defines two classes: the vector and string. vector is intended to replace the built-in C++ array, which causes no end of troube. The problem with the built in C++ array is that it doe

如何在foreach中删除一个集合中的元素，其实很简单，只用一个递归就可以了，例如下面的一个代码判断一个listbox里面的items都是checkbox其中被选中的全部都删除 void removef() { foreach (CheckBox item in lst.Items) { i
