Question

Consider that individual nodes in an unsorted linked list have the following definition class Vector public: Vector(int s = 0)( // makes Size //allocates s space, // makes all entries s, kes all entries e Vector (const Vector & rhs) // copy constructor // makes self a deep copy of rhs Vector operator (const Vector & rhs)(// makes self a deep copy of rhs nVector default destructor int & operator[] (int index){ if 0く-posくsize // // returns entries[index] int sz(){// returns the # of entries private: int size; int *entries; //store the # of elements used 3; ostream & operator<< (ostream & out, Vector & rhs);

Please give a answer to both tasks with a screenshot of the running file.

Thanks

Vector.h

-------------------------------

#ifndef VECTOR_H
#define VECTOR_H
#include"iostream"
using namespace std;
class Vector
{
private:
    int size;
    int * entries;
public:
    Vector(int s=0);
    Vector(const Vector &rhs);
    Vector operator = (const Vector &rhs);
    friend ostream & operator << (ostream& os,const Vector & rhs);

    ~Vector();
    int & operator[](int index);
    int sz();
};

#endif // VECTOR_H

Vector.cpp

-------------------------

#include "vector.h"
#include <cstring>
Vector::Vector(int s)
{
    this->size = s;
    this->entries = new int[s];
}

Vector::Vector(const Vector &rhs){
    this->size = rhs.size;
    this->entries = new int[this->size];
    memccpy(this->entries,rhs.entries,rhs.size,sizeof(int));
}

Vector Vector:: operator = (const Vector &rhs){
   this->size = rhs.size;
   this->entries = new int[this->size];
    //memcpy(this->entries,rhs.entries,rhs.size);
    for(int i = 0 ; i< rhs.size ; i++){
        this->entries[i] = rhs.entries[i];
    }
    return *this;
}

Vector::~Vector(){

}

ostream& operator << (ostream& os,const Vector &rhs){
    os<<"printing Vector"<<endl;

    for(int i = 0 ; i < rhs.size;i++){
        cout<<rhs.entries[i]<<endl;
    }
    return os;
}

int & Vector::operator[](int index){
    return entries[index];
}

int Vector::sz(){
    return size;
}

Main.cpp

------------------------

#include <iostream>
#include<vector.h>
using namespace std;

int main(int argc, char *argv[])
{
    Vector test(10);
    Vector *vecPtr;
    Vector exam(5);
    for(int i = 0 ; i < test.sz();i++){
        test[i]= i;
    }
    cout<<"test initially is:";
    cout<<test<<endl;

    exam = test;
    cout<<"After exam = test, exam is :";
    cout<<exam <<endl;

    {
        Vector sqrs(10);
        cout<<"The Squares are :";
        for(int i = 0 ; i < sqrs.sz();i++){
            sqrs[i] = i*i;
        }
        vecPtr= &sqrs;
        cout<<sqrs<<endl;
    }
    return 0;
}
