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: ...
局部作用域(代码块作用域、函数原型作用域与函数作用域,Block scope&Function prototype scope&Function scope):在声明所在的代码块、函数内可见,包括switch、for等语句中暂时声明的变量、普通声明的变量、函数参数、函数中的static变量。 类作用域、枚举作用域(Class scope & Enumration scope):在结构体、类、枚举中...
The object is to be stored in memory or in a register, if available The object has internal, external, or no linkage The object can be referenced throughout a program or only within the function, block, or source file where the variable is defined The storage duration for the object...
