myClass()=delete;//表⽰删除默认构造函数 myClass()=default;//表⽰默认存在构造函数 当类中含有不能默认拷贝成员变量时，可以禁⽌默认构造函数的⽣成，myClass(const myClass&)=delete;//表⽰删除默认拷贝构造函数，即不能进⾏默认拷贝 myClass & operatir=(const myClass&)=delete;//表⽰删除...
1. 禁止使用编译器默认生成的函数 假如上面的几个函数中,不想使用其中某个,可以将其定义为private,或者使用=delete。 #include<iostream>usingnamespacestd;classDataOnly{public:DataOnly() {} ~DataOnly() {}DataOnly(constDataOnly & rhs) =delete;//禁止使用该函数DataOnly &operator=(constDataOnly & rhs)...
default delete
但是手动编写存在两个问题:1. 程序员工作量变大 2. 没有编译器自动生成的默认特殊构造函数效率高。 不能看到上面的例子中,工作量不大,就认为上面的第一个问题不存在。请看下面的例子: class A{public:A(intii,charcc):i(ii),c(cc){}A(constA&a);private:inti;charc;}; ...
//类中的const默认还是可以修改,与C语言const一致 void main() { goodclass good1; goodclass::show(good1); const int *px = &(good1.data); std::cout << px << std::endl; int *p = const_cast<int *> (px); *p = 123; std::cout << *px << " " << *p << " " << good1....
