Class design 'dilemma' -


I have never designed a proper class, so bear with me.

Let's say we have the project class. So suppose we have a project group class, which has members like project class, as well as of project s

There is a list. Must be a super class of

Project Group Project or Project Group Project should be specialization and prior Should be a subclass of the latter?

I will not bother you with the theory , because you get quick answers Are in a hurry. So here it goes:

If your two classes are actually mentioned then they should be related to heritage, then from project group to project class Should get. How would it be like the C #: 

  the public class looks like a project group: Project ... if they are not, but they belong to some common class Uses members (which defines their state and some functionality in that situation), I will write an interface and apply it in both classes. C # code again:  
  public interface ICMMST ... Public Sector Project: ICMMS Tate ... public class project group: Aiseedomenstet {Aianmumerebl & lt; ICMMSTAT & gt; Projects ...}  
 
 Edit 
 
 If your classes are actually  project  and  project groups  and They have both in common (for example) such as  id  and  names , they should not be inherited yet. They have qualities with the same name, but they are basically different bodies. 
 
 They can implement a  ICommonEntity  interface - it is used when they have the same status + functionality, But the functionality behaves differently in each of them  
  •   General Entity  - The functionality is completely identical when using it;   
     Then your component can be an interface or a square (using the overall pattern).  
     The direct fortune between two classes is more suitable, where the institutions give signals to be related to each other. Like the  user  and  person  classes. They may in any way be deprived, depending on the business scenario. 
     
      class user: person  
     
     This will be the situation where you have an application with contacts, some of them are users of the same application. 
     
      class person: user  
     
     This will be a web site where you can register as a user. If you fill out some personal details then your user data type becomes  person .

    Eclipse CDT variable colors in editor -

    I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
