函数重载和函数重写之间的区别是什么 [英] What is the differene between function overloading and function overriding

问题描述

大家好，

只是我想知道

1>函数重载和函数重写之间有什么区别

2>什么是多态

解决方案

函数重载和函数重写之间的区别是：



当你崩溃时有几个具有相同名称的功能，但它可以采取几种不同的输入：

覆盖替换现有函数并在继承基类时发生：

多态性 [ ^ ]

函数重载具有一组具有相同名称但参数不同的函数。 （技术上在.NET中，但不是C＃返回类型计数）。覆盖是在子类中具有一个覆盖父类中的函数的函数。



多态性需要更多的讨论，但在软件开发中是一个重要的事情。至少在过去的二十年里。如建议的那样 - 使用Google。

重载

Hi to all,
just i want to know

2> what is polymorphism

解决方案

The difference between function overloading and function overriding is:

Overloding is when you have several functions with the same name, but that it can take several different inputs:

Overrides replaces an existing function and happens in inheriting a base class:

Polymorphism[^]

Function overloading is having a set of functions with the same name but different parameters. (Technically in .NET but not C# return type counts also). Overriding is having a function in a child class that overrides one in a parent class.

Polymorphism needs more of a discussion but had been a major thing in software development for at least the last twenty years. As suggested - use Google.
