Question

C++ computer science

Given the partial class HardDrive implementation below, implement all of the following:

1: default constructor that initialized the attributes with proper default data of your choice.

2: destructor() method, that releases all the dynamically allocated memory.

3: copy constructor() method: That properly manages the dynamic array when the object is passed by value to a function as a parameter.

4: overload the assignment operator: To properly handle copying the dynamic array when one object is assigned to another object.

Hint: Rule of three.

5: getters and setters (methods) for each class member: for accessing and updating the values of the fields.

Hint: final assignment.

class HardDrive       {

     private:

           string serialNo;

           double CapacityInGBs;

           string Brand;

           int RotationalSpeedRperMin;  // revolutions per minute

           int numberOfExtraFeatures;

           string* otherFeatures;

          

public:

HardDrive(string _serialNo_, double _CapacityInGBs_, string _Brand_, int _RotationalSpeedRperMin_, int numberOfExtraFeatures_) {

           serialNo = _serialNo_;

           CapacityInGBs = _CapacityInGBs_;

           Brand = _Brand_;

           RotationalSpeedRperMin = _RotationalSpeedRperMin_;

           numberOfExtraFeatures = numberOfExtraFeatures_;

           otherFeatures = new string[numberOfExtraFeatures];

     }

  

      // Your implementations

} // end of class

Answer 1

1)

HardDrive::HardDrive() {

seriaNo = "1234";

CapacityInGBs = 512;

Brand = "Dell";

RotationalSpeedRperMin = 7200;

numberOfExtraFeatures = 0;

otherFeatures = {};

}

2)

HardDrive:: ~HardDrive() {

delete[] otherFeatures;

}

3)

HardDrive::HardDrive (const HardDrive &hd) {

this->serialNo = hd.getSerialNo();

this->CapacityInGBs = hd.getCapacityInGBs();

this->Brand = hd.getBrand();

this->RotationalSpeedRperMin = hd.getRotationalSpeedRperMin();

this->numberOfExtraFeatures = hd.getNumberOfExtraFeatures();

this->otherFeatures = new string[this->numberOfExtraFeatures];

for (int i=0; i<this->numberOfExtraFeatures; i++ ) {

this->otherFeatures[i] = hd->getOtherFeatures()[i];

}

}
