class Person { //field name:string; //constructor constructor(name:string) { this.name = name; } //function speakName():void { console.log("Name is : "+this.name) } } 枚举与其他编程语言一样,枚举是由一组命名值组成的数据类型。 名称通常是充当常量的标识符。 ES6 中引入了枚举。enum Dire...
In C++ programming, initializing an array within a constructor is a common practice, especially in object-oriented design. Consider a class named DataContainer that encapsulates an integer array. Our goal is to ensure this array is initialized appropriately when an object of the class is created....

When used in overloading, such functions are called factory methods. We can use them to implement the concept of constructor overloading in Python. Example: classdelftstack(object):def__init__(self,a):self.ans="a"@classmethoddeffirst(cls):return"first"@classmethoddefsecond(cls):return"secon...
