plz help me wid the class design

[48T7M4Gy]

Which class? Pick a name for it - start somewhere :)

[abcdk]

class student
{
string regno;
string name;
aoi a;
public:
void getdetails();
// void check();
void display();
friend void addarea(student);
};

class aoi
{
string area_id;
string workdone;
string pub_details;
public:
void addarea(student);
void checkcriteria();
};


is this ok?

[48T7M4Gy]

use code tags and indents. What's an aoi? Must be AreaOfInterest.

[abcdk]

yaa its areaOfInterest

[48T7M4Gy]

OK concentrate on the student class. You need a constructor, destructor, int IDNo and private properties string name and two methods getID() and getName(). Do AreaOfInterest class later.

[48T7M4Gy]

class Student{
private:
   int IDNo;
   string Name;
 
public:
Student( int id, string name ) {
      IDNo= id;
      Name = name;
   }

  ~Student()
  {
  }
 
   string getName() {
      return Name;
   }
 
   int getID() {
      return IDNo;
   }
};

thnx..and do i need to pass object of one class into another?

[48T7M4Gy]

Well, the short answer is yes but you should think about AreaOfInterest. Hint: get the basics of that right first. Use the Student class as a pattern.

[abcdk]

how about this?

class aoi
{
	string area_id;
	string workdone;
	string publiction;
	public:
		aoi(string area,string wd,string pub)
		{
			area_id=area;
			workdone=wd;
			publication=pub;
		}
		
		~aoi()
		{
		}
		
		string getareaid(student)
		return area_id;
}
