这对于在C/C++或任何其他需要存储函数先前状态的应用程序中实现协程非常有用。 // C++ program to demonstrate // the use of static Static // variables in a Function #include <iostream> #include <string> using namespace std; void demo() { // static variable static int count = 0; cout << ...
一个类的static member也称为"class variable", 这是因为它是该类所有对象中共享的,即它的值不会因所属该类对象的不同而发生改变。 它可以用于统计目前该类实例化了多少对象: // static members in classes #include <iostream> using namespace std; class Dummy { public: static int n; Dummy () { n...
declaring a member function as const is a promise not to modify the object of which the function is a member; static data members must be defined (exactly once) outside the class body; 5. Static in C A static variable inside a function keeps its value between invocations. eg: ...
