What management systems (Updates) for things like this

       2019.7.12 Update record ：

        Many people come to roast that the code I wrote before is smelly and long , So today we updated the following , It really hasn't changed much , But there are many good reviews , I'm going to write back C++ Class version

        No one is required to download , No one is required to give points , Direct disclosure , Sign in csdn Just copy and paste

codeblocks Replace the text shortcut key with ：ctrl+R

Replace the text shortcut key with ：ctrl+h

The source code is left here ：

/*C++ Structure version , With notes */
/*
v0.3 Update log ：2019.6.30 to update .
 The main updates are ：
1、 Put the original input part , The output part is changed to an inline function , Reduce code , Run faster 
2、 The input and output contents only need to be changed in these two functions 
3、 Try changing the next version to include class content 
4、 Try changing the next version to windowed generated code , Just poke the mouse 
5、 Actually, I didn't do much , But it's cool to write notes , Just write 
~OuO~

//VS Common shortcut key : Sequential press  ctrl+k ctrl+d—— Automatic code formatting 
//ctrl+h—— Quick replace text , If there is a selected part, only the selected part will be replaced by default , On the contrary, global replacement , Including comments will also be replaced 
//Codeblocks Common shortcut key ：alt+l  Call out the menu , choice Astyle, Can automatically organize the code format 
//ctrl+r—— Quick replace text , The effect same as above 
#include<iostream>
#include<string>
#include<algorithm>
