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 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.

Answer 1

#include <iostream>

using namespace std;

class CameraPhone:Phone{

int imageSize,memorySize;

public:

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

int numPictures(){

return memorySize-imageSize;

}

}

int main(){}
