Question

**** IN C++ ****

1) Modify the class pointerDataClass so the main function below is working properly. Use deep copy.

int main()
{
pointerDataClass list1(10);
list1.insertAt(0, 50);
list1.insertAt(4, 30);
list1.insertAt(8, 60);
cout<<"List1: " < list1.displayData();
cout<<"List 2: "< pointerDataClass list2(list1);
list2.displayData();
list1.insertAt(4,100);
cout<<"List1: (after insert 100 at indext 4) " < list1.displayData();
cout<<"List 2: "< list2.displayData();
return 0;
}

Code:

#include

using namespace std;

class pointerDataClass

{
int maxSize;
int length;
int *p;
public:
pointerDataClass(int size);
~pointerDataClass();
void insertAt(int index, int num);
void displayData();

};

pointerDataClass::pointerDataClass(int size)
{
maxSize = size;
p=new int[maxSize];
length = 0;
}

pointerDataClass::~pointerDataClass()
{
delete[] p;
}

void pointerDataClass::insertAt(int index, int num)
{
for(int i=length-1; i>=index; i--)
{
p[i] = p[i-1];
}
p[index]=num;
length++;
}

void pointerDataClass::displayData()
{
for(int i=0;i {
cout< }
cout< }

int main()
{
pointerDataClass list11(10);
for (int i =0;i<10;i++)
{
list11.insertAt(i, i);
}
list11.displayData();
return 0;
}

SOLUTION-
I have solve the problem in C++ code with comments and output screenshot for easy understanding :)

CODE-

#include<iostream>
using namespace std;

class pointerDataClass
{
   int maxSize;
   int length;
   int *p;
public:
   pointerDataClass(int size);
   ~pointerDataClass();
   pointerDataClass(const pointerDataClass&other);
   void insertAt(int index, int num);
   void displayData();
   void get();//get the length of the arrray
};

pointerDataClass::pointerDataClass(int size)
{
   this->p = new int[size];
   this->maxSize = size;
   this->length = 0;
   for (int index = 0; index < size; index++)
       this->p[index] = 0;
}
pointerDataClass::~pointerDataClass()
{
   delete this->p;
}
pointerDataClass::pointerDataClass(const pointerDataClass&other)
{
   this->maxSize = other.maxSize;
   this->length = other.length;
   this->p = new int[this->maxSize];
   for (int index = 0; index < other.maxSize; index++)
       this->p[index] = other.p[index];
}
void pointerDataClass::insertAt(int index, int num) \
{
   this->p[index] = num;
   this->length++;
}
void pointerDataClass::displayData()
{
   for (int index = 0; index < maxSize; index++)
       cout << this->p[index] << " ";
   cout << endl;
}
void pointerDataClass::get()
{
   cout << "Length: " << length << endl;
}

int main()
{
   pointerDataClass list1(10);
   list1.insertAt(0, 50);
   list1.insertAt(4, 30);
   list1.insertAt(8, 60);
   cout << "List1: " << endl;
   list1.displayData();
   cout << "List 2: " << endl;
   pointerDataClass list2(list1);
   list2.displayData();
   list1.insertAt(4, 100);
   cout << "List1: (after insert 100 at indext 4) " << endl;
   list1.displayData();
   cout << "List 2: " << endl;
   list2.displayData();
   list1.get();
   list2.get();
   system("pause");
   return 0;
}
