This has nothing to do with Graphics.

I only want p1.draw() to be printed on the location ( 5, 5 ) ( x, y ) in the page.

You are not moving the cursor at right place before you do a "cout"
Ycan move cursor by including one more function in your point class
in point.h
add a member funtion in the point class
C++ Syntax (Toggle Plain Text) 
  1. void gotoxy(int , int ) const ;
in point .cpp add following.
C++ Syntax (Toggle Plain Text) 
  1.  
  2.  
  3. void Point::gotoxy(int x, int y) const
  4. {
  5. 	HANDLE hConsoleOutput;
  6. 	COORD Cursor_Pos = {x, y};
  7.  
  8. 	hConsoleOutput = GetStdHandle(STD_OUTPUT_HANDLE);
  9. 	SetConsoleCursorPosition(hConsoleOutput, Cursor_Pos);
  10. }

use it in your draw member function
C++ Syntax (Toggle Plain Text) 
  1. void Point::draw() const
  2. {
  3. 	gotoxy(x,y);
  4. 	cout<<".";
  5. }

Thank You Very much. I can't begin to express my gratitude for helping me out on this. Now i can add the rest of my classes without any problem.

Thank You.

Cheers...
