在口语交流中,我们可以这样描述这些示例: “In the first example, the classNonCopyableexplicitly deletes its copy constructor and copy assignment operator, so trying to copy an instance ofNonCopyableresults in a compile error. In the second example, the functionfooexplicitly deletes its overload that ...
对象中包含有其他对象时,先初始化别人,再初始化自己 对象中包含有其他对象时,先析构自己,再析构别人 默认构造函数是浅拷贝 5)拷贝构造函数的深拷贝与浅拷贝 【注意】两个已经初始化完毕的对象 用= 号赋值不会调用构造函数,但是会调用拷贝构造函数 6)构造函数初始化列表 类中含有const属性变量,必须在构造函数的初...

constructor 从上述代码表现来看,移动构造只参与了重载决议,未参与链接和运行期运行! 最后我们再尝试一个移动构造参与链接器链接的版本: #include<iostream>classTest{public:Test(){std::cout<<"constructor\n";}Test(constTest&test){std::cout<<"copy constructor\n";}Test&operator=(constTest&test){std::co...
