设计模式_单例模式

单例模式就是保证一个类仅有一个实例，并提供一个访问它的全局访问点

#include<iostream>class singleObject{public:static singleObject* getInstance();inline void show(){ std::cout << "帝江最帅" << std::endl; }private:singleObject(){};  //核心：构造函数私有static singleObject *mysingleObject;};singleObject *singleObject::getInstance(){if (!mysingleObject){mysingleObject = new singleObject();}return mysingleObject;}singleObject* singleObject::mysingleObject = NULL;int main(){singleObject * single = singleObject::getInstance();single->show();system("pause");return 0;}
