4)对于基类成员的初始化:与第3点一样,只能使用Initializer List调用基类的参数化构造函数。 #include<iostream>usingnamespacestd;classA{inti;public:A(int);};A::A(intarg){i=arg;cout<<"A's Constructor called: Value of i: "<<i<<endl;}// Class B is derived from AclassB:A{public:B(int)...

A constructor in C# is called when a class or struct is created. Use constructors to set defaults, limit instantiation, and write flexible, easy-to-read code.

若要自己定义初始化的过程,可以重写init方法,来添加额外的工作。(用途类似C++ 的构造函数constructor) 方法 Objective-C 中的类可以声明两种类型的方法:实例方法和类方法。实例方法就是一个方法,它在类的一个具体实例的范围内执行。也就是说,在你调用一个实例方法前,你必须首先创建类的一个实例。而类方法,比较起来...
