CHALLENGE:

Assume  the existence of a Phone class . Define a derived class , CameraPhone that contains two data members: an integer  named , imageSize, representing the size in megapixels of each picture, and an integer  named  memorySize, representing the number of gigabytes in the camera’s memory. There is a constructor  that accepts two integer  parameters  corresponding to the above two data members and which are used to initialize  the respective data members. There is also a function named  numPictures that returns (as an integer ) the number of pictures the camera’s memory can hold.
