# C++ Implement A Class With No Duplicates

**Question**

Implement the following Set class. A set is a collection of items with no duplicates. The following class implements a set of integers.

#ifndef SET_H

#define SET_H

#include <iostream>

#include <vector>

using namespace std;

class Set

{

// friend operator functions

friend ostream &operator<<(ostream & out, const Set & s);

friend istream &operator>>(istream & in, Set & s);

public:

// Constructors

Set(); // default constructor

Set(const Set & s); // copy constructor

// destructor

~Set();

// operator functions

Set operator||(Set & s); // union of the set with the set s

Set operator&&(Set & s); // intersection of the set with the set s

const Set& operator=(const Set & s); // assignment

bool operator==(const Set & s); // equality

int& operator[](int index); // returns modifiable lvalue

int operator[](int index) const; // returns rvalue

// Set membership functions

bool member(int m); // The integer m is a member

void add(int m); // add the integer m to the set

void remove(int m); // remove the integer m from the set

private:

vector<int> _s;

};

#endif

The member functions must be written in a file Set.cpp. You are required to provide a driver program for the above class as well.

**Summary**

The question belongs to Computer Science and it discusses about implementing a set class of data with no duplicates using C++. Apart from this, a driver program for the class.**Total Word Count NA**

JaneteHello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
