Beginner's understanding and questions about MVC...

M indicates data.
V indicates the view, which is displayed.
C Represents data operations.

For example:
Class M
{
// Store data
Int X;
};

Class V
{
// Screen Display
Void draw ();
};

Class C
{
// Read data
Void loaddata ();
};

V c inevitably uses M data, But how do they relate to M.
Add a pointer to m in v c?
M * data;
Void setdata (M * aData ).

In this way, all v c instances must be added as above.CodeAt the same time, if another class is added to v c and the class uses M data,
This is not to add the above Code to the newly added class... it causes trouble.

I don't know if the MVC mode is used in this way. How can I design it to meet the above usage?
