静态函数/变量 [英] static function/variable

问题描述

我刚刚开始编程在c ++这个静态变量/函数的概念不清楚我是什么，这是使用，是有任何其他替代这个!!!

i just started programming in c++ this concept of static variable/function wasn't clear to me..why is this used and is there any other alternative of this!!!

推荐答案

static可能有点混乱，因为它根据使用的位置而略有不同。

static can be a little confusing because of its slightly different meaning depending upon where it is used.

在本地声明的静态变量将通过对该函数的连续调用保持其值（如netrom的示例）

A static variable, declared locally, will keep its value over successive calls to that function (as in netrom's example)

静态成员变量不属于该类。

A static member variable does not belong to the class.

类，可以在不声明该类的实例的情况下使用。

A static function, declared in a class, can be used without declaring an instance of that class.
