اريد تقييمكم على البرنامج + شرح بسيط لبعض الفقرات =)

السلام عليكــم ورحمـة الله وبركاتــه ،،

• Write a Mobile class, which contains three attributes: colour, make, and model.
  • All attributes should be represented as strings.
    
  • The model and make of a mobile are not modifiable
    
  • All mobiles are made by Nokia (i.e. the make is the same for all mobiles)
    

• Write a constructor for the class.
  • If you were not able to write a default constructor, what do you think is the reason for this inability?
    
  • Are there any attributes that cannot be initialized inside the constructor? What are they?
    

• Add three methods (member functions) to the class:
  • First method should be called ring which displays on the screen "ring! ring! ring!". This method should not change any of the attributes values.
    

• • Second method prints on the screen the mobile's description (colour, make and model of the mobile.)
    

• • Last method is called changeCover, which sets the colour of the mobile to a given colour.
    

• Add another method (member function) called isTheSame which takes a Mobile object as a parameter. It should return true if the given Mobile object is the same as this mobile. Two mobiles are the same if they have the same make and model.
  

• Test your class by creating a silver, Nokia, 6600 mobile object. Then send it a message to display its information.
  

Change the cover of the mobile to a red one, then again send it a message to display its information.

Create another black, Nokia, 3310 mobile object, then ask it if it was the same as the first mobile (the one you have created above).

• Change the isTheSame method in question 4 to be a global function that is a friend of the class.
  • Do you need to change the parameters and why?
    
  • Change the test case in question 5 to reflect the modification of the function.
