C++禁止使用拷贝构造函数和赋值运算符方法

1.将拷贝构造函数和赋值运算符声明为私有，并不予实现

class Uncopyable  
{  
private:  
    Uncopyable(const Uncopyable &); // 阻止copying  
    Uncopyable &operator=(const Uncopyable &);  
};  

2.使用delete

class Uncopyable  
{  

    Uncopyable(const Uncopyable &) =delete; // 阻止copying  
    Uncopyable &operator=(const Uncopyable &)=delete;  
};
