Configuration process

1. Download vs2017

Download a c ++ configuration environment
2. Download git

3. A super save the library to your library

4. In a file directory git bush, save the library file to your local

5. The original Java files into cpp file

6. copy the source code and header files into the vs

Code

In the document, I will issue MakeFormula string Calculator :: random () function is generated in the main function, so that when called repeatedly will not appear on the same formula

Use github clone projects and submit code
Open git, git push input file in the local

2. Upload complete

Feelings and sharing

The head of the blog is really great, because we are not familiar with git and vs2017, this time work experience, to git a certain understanding, to know how to download files and upload files above, I would like to work in the future will also need their own to learn new tools, so you need to acquire knowledge in the ever growing and learning, it will not be eliminated by the times.
