For test Code highlight

I do not believe the 优快云 will put energy to implement all function in original xheiditor in MarkDown editor.

Code sytle in C

int main(void){
    printf("优快云, please do better !");
}

Code sytle in Java

class 优快云 extends Markdown{
    private String mBug;
    public String getBug(){
        return new String(mBug);
    }
}

Code sytle in C++

class 优快云 extends Markdown{
    private String mBug;
    public String getBug(){
        return new String(mBug);
    }
    // override abstract function
    public void getText(){
        cout<< "I do not like this code snippet, which does
        not have the same strong character in original editor"
        << endl;
    }
}

Code sytle in C#

using System.Windows.Forms;

class Program
{
    static void Main()
    {
        MessageBox.Show("Hello, world!");
    }
}
