Please provide the c++ code as well as a screenshot of the working program!
Thanks Header File override C++ vector definition #ifndef VECTOR H #define VECTOR H class Vector public: Vector 0; ll default constructor Vector (int s); ll makes size //allocates s space ll e.g. entries new int[size] ll makes all entries 0 Vector (const Vector & other); Il copy constructor ll makes a deep copy Vector 0 ll default destructor Il Prints out the vector void print 0; void set int val, int pos); Il if 0 pos

Explanation / Answer

/*

#ifndef VECTOR_H
#define   VECTOR_H
class Vector{
private:
    int size;   //set the no of elements used
    int *entries;   //point to array of int with size entries, eg- entries=new int[size]
public:
    Vector();       //default constructor
    Vector(int s); //make size=s, allocate s space, e.g- entries=new int[size],make all entries 0
    Vector(const Vector &other);//copy constructor, makes a deep copy
    ~Vector();      //default destructor
    void print();   //prints out the vector
    void set(int val,int pos);//if0<=pos<size, store val at pos in entries, otherwise show error mmessage
};

#endif   /* VECTOR_H */

//Vectors.cpp- implementation file

#include<iostream>
#include"Vector.h"

using namespace std;

Vector::Vector(){   //default constructor
    size=0;
    entries=NULL;
}
Vector::Vector(int s){
    size=s;
    entries=new int[size];
    for(int i=0;i<s;i++)
        entries[i]=0;
}
Vector::Vector(const Vector& other){//copy constructor
   size=other.size;
    entries=other.entries;
}
Vector::~Vector(){
    delete []entries;
    size=0;
}
void Vector::set(int val, int pos){
    if(pos<0||pos>=size)
        cout<<"Invalid input for position; it must be between 0 and "<<size<<endl;
    else
        entries[pos]=val;
}
void Vector::print(){
    cout<<"[";
    for(int i=0;i<size;i++)//if the entry to be displayed is not the last entry put a space after it
        if(i==size-1)
            cout<<entries[i];
        else
            cout<<entries[i]<<" ";
    cout<<"] ";
}

//main file

#include <cstdlib>
#include<iostream>

using namespace std;

int main() {
    Vector a,b(3),c(3);
  
    cout<<"Vector a:- ";
   a.print();
   cout<<"Vector b:- ";
    b.print();
   
   cout<<"O/P for c.set(0,-1):-"<<endl;

   c.set(4,3);
   cout<<"c= ";
   c.print();
  
   Vector d(c);
   cout<<"d= ";
   d.print();
  
   d.set(0,1);
   cout<<"new value of d= ";
    d.print();
    return 0;
