C++：

C++ It's a knowledgeable child , Relatively young , It's not that cold .

I ：C acutely , Shall we put the elephant in the refrigerator ？

C++： roll

It's not very cold ？

I ： Well, I was wrong , dear C++, Let's put the elephant in the refrigerator .

C++： Good mamda , The data types of elephants have been defined , Refrigerators have been defined , You need to construct one each .

I ： well .

So I looked through the document and found out that new To construct the

I ：OK, dear C++, I want to build an elephant .

C++： well , There are ways to build elephants 13 individual , Which one would you like to choose ？

I ...

I ： Let me introduce you .

C++：OK, First, you can construct on the stack , The advantage of this is that it can facilitate resource management , And the grammar is better , You can use RAII, If you don't know something RAII, You can go to cppreference Check it up , Of course, you can also build on the heap , You can build a big, big elephant , also .......

A month later ,C++ It's over . I'm full of whiskers, too ... After shaving, go on working

I ： well ,C++, I'll build an elephant on top of the stack .

C++： You don't love me .

I ：？？？

C++： You didn't even say “ dear ”.

I ...

I ： I just want a simple one , Default is good .

C++： well , Constructed a , You can choose how to initialize it , Yes 13 Initialization methods , The latest unified initialization is recommended .

I ...

I ： Unified initialization

C++： well , We can build refrigerators .

I ： good ...

After a month of choice , Finally, the refrigerator was constructed .

C++： well , The refrigerator provides addElephant Method , It can be used directly .

I ： Wow, that's great , well , I use this method .

C++： This method provides multiple overloads , You can copy , Move , You can also forward it directly , Save on building an elephant before moving into the refrigerator .

I ：... Why didn't you say

C++： Why didn't you ask .

I ： Just use the mobile one .

C++：OK, Please use std::move Turn the constructed elephant into a right-hand reference .

I'm a face of meng , But do it .

I ： Okay

C++：OK, It's in the fridge , Very fast .

All of a sudden

C++： Wrong report... Wrong report , Molecules and atoms are not convertible types , There is no relationship between the giant panda and Edison + Operators, etc 1556 Item error .

I .........

I ： Look for information online , Just look at the last line , OK, look at it . Um. , It looks like number one 31 There's a mistake , What is the mistake ？ I didn't make myself clear when I reported the wrong information . Make any changes . compile , function .

C++： well , It's hip circumference 12 rice , The left arm is long 13 rice , The right arm is long 14 rice , Like male elephants , No marriage, no children , It's good to be tutored since childhood , The African female elephant, who is familiar with the four books and five classics, puts orange in it , Fifty meters high , Sixty meters wide , Three hundred meters thick , It's three hundred degrees below zero , The brand of refrigerant is Huche brand , Rated voltage 220V In the refrigerator .

I ... A long sigh of relief .

C#：

I ： I want to put the elephant in the refrigerator .

C#： Good master , My dad, Microsoft, has written elephants , Also wrote the refrigerator class , You only need new Just a moment .

I ：OK,new Okay , Put it in the refrigerator .

C#： well , Has been put in , Using the expansion method of refrigerator addElephant<>() Method .

You can also bring him to me , We can work together . You can also C++ The finished work is exported to binary form , I can use it directly .

I ： Well, thank you , A: no, no .
