Question

Having troubles with the subject inheritence. This is a myProgramming question using c++. I was hoping to get some help. Thank you.

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 megabytes of each picture, and an integer named memorySize, representing the number of megabytes 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

Below is your code. I am assuming Phone class is there, and as I dont know it I cannot write the main function. Let me know in comments if you have any issue: -

class CameraPhone : public Phone { // Declaration of CameraPhone class extending Phone classs

public:

CameraPhone(int imageSize,int memorySize); // Parametrized Contructor

int numPictures(); // function declaration to get number of pictures = memorySize / imageSize

private:

//instance variable declaration

int imageSize;

int memorySize;

};

//Constructor definition with initializer List

CameraPhone::CameraPhone(int imageSize,int memorySize) : imageSize(imageSize), memorySize(memorySize) {}

//Method definition to get number of Pictures

int CameraPhone::numPictures() { return memorySize/imageSize; }
