C++中的构造函数(Constructor) C++中有这么一种特殊的函数,它在类里,与类名同名,且没有返回值的一个函数,只要我们定义一个类的对象,系统就会自动调用它,进行专门的初始化对象用,而大多数情况下,因为我们没有定义构造函数,系统会默认生成一个默认形式、隐藏着的构造函数,这个构造函数的函数体是空着的,因此不具有...

(原創) constructor不能呼叫其他constructor (C/C++) 由於data member都需要初始化,所以會想將初始化data member的程式寫在某一個constructor中,這樣其他constructor就可以呼叫這個constructor達到code reuse,但我發現C++竟然不能這樣寫。 1#include <iostream>
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.
MyClass(charc) : MyClass(1.2) { } MyClass(doubled) : MyClass('m') { } }; The first constructor will delegate to the second constructor, which delegates back to the first one. The behaviour of such code is undefined by the standard and depends on the compiler. ...
