Question

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.

Explanation / Answer

class CameraPhone :public Phone {

public:

CameraPhone(int, int);

int numPictures();

private:

int imageSize;

int memorySize;

};

CameraPhone::CameraPhone(int myimageSize, int mymemorySize) {

imageSize = myimageSize;

memorySize = mymemorySize;

}

int CameraPhone::numPictures() {

return memorySize / imageSize;

}
