今日份总结
Polymorphism (多态)

在C++,多态，一个东西多种形式

1.多态具体表现:在C++中，有两种形式，一种是编译时刻的一个多态，运行时刻的一个多态。运行就是变成一个进程在执行

(1)Compile Time Polymorphism编译时刻多态:
Function Overloading函数重载，
Operator Overloading运算符重载

(2)Run Time Polymorphism运行时刻多态:
Virtual Function虚函数

2.什么是重载:
if we creat two or more members having the same name but different in number or type of parameter .it is known as c++ overloading.
在C++中，如果我们创建两个或以上的成员，它们有相同的
名字，但是参数不同(数量或类型不一样)，我们称这种情况
为“重载".

函数重载: Function Overloading
运算符重载: Operator Overloading

3.1 函数重载
(1) 什么是函数重载?

同一个作用域内，多个函数同名，但是参数个数或类型不一样。

(2) 为什么需要函数重载呢?

举个例子:

C: sum.c

int sum(int a, int b)

{

}

double sum_xx(double a, double b)

{}

...

为相同的功能，取不同的函数名，并且在调用的时候

你还要仔细去区分它!!!

C++: sum.cpp

int sum(int a, int b)

{}

double sum(double a, double b)

{}

...

sum(3.5, 4.7);

(3) C++中的函数重载是如何实现的吗？

实现原理：

在C++中，重载函数经过编译器编译后，编译器会整

It’s hard to elucidate or even just verbalise something, especially when we talk about the emotional things.
Just image that, you are walking on a street, in an afternoon of the deep Autumn. You see the yellow and golden leaves on the ground, on the car, on people’s head. You exhale, see the steam in the air, you lower your head, and miss someone.
I guess that’s how human being creat the invisible connection between each other, which they will hold across their entire lives.
Maybe that’s why we are human beings.
