在cpp中,对于成员是另一个类的类来说,使用初始化列表可以少调用一次调用默认构造的过程,算是性能要求;而针对const成员和引用成员,此类成员的初始化必须放初始化列表中。如下: classA{ public: A(intx):a(x) {} constinta; }; classB{ public: B(intx) :a(x) {} int& a; }; classC{ p

const 的指针与引用指针 指向常量的指针(pointer to const) 自身是常量的指针(常量指针,const pointer) 引用 指向常量的引用(reference to const) 没有const reference,因为引用只是对象的别名,引用不是对象,不能用 const 修饰(为了方便记忆可以想成)被 const 修饰(在 const 后面)的值不可改变,如下文使用例子中...
