Question

C++ Programming

Create a set class. Implement the set operators: u, n-Δ and boolean functions to test for OS, and C. Implement functions to add members to a set, delete members from a set, and display a set. Be sure to test all functions

Answer 1

C++ PROGRAM:

#include <iostream>
#include <set>
#include <iterator>
using namespace std;
class setClass
{
set <int> elements;
int values;
public:
setClass()
{
}
void setMethod(int val, set <int> elem)
{
values=val;
elements = elem;
}
int getMethod()
{
return values;
}
set<int> getSetMethod()
{
return elements;
}
bool addMembers()
{
set <int> ::iterator itr;
for (itr = elements.begin(); itr != elements.end(); ++itr)
{
if (*itr == values)
{
return false;
exit(0);
}
}
  
return true;
}
bool delMembers(int val)
{
set <int> ::iterator itr;
for (itr = elements.begin(); itr != elements.end(); ++itr)
{
if (*itr == val) {
return true;
exit(0);
}
}
  
return false;
}
void display(set<int>setter)
{
set <int> ::iterator itr;
cout << "\nThe set values is : ";
for (itr = setter.begin(); itr != setter.end(); ++itr)
{
cout << '\t' << *itr;
}
cout << endl;
}

};
int main()
{
set <int> setter;
setClass s;
int val,choice=1,op;
cout << " WELCOME TO SET GENERATION PROGRAM " << endl;
while (choice == 1)
{
cout << "Your options:\n1.Press 1 for 'add' elements in set\n2.Press 2 for 'Delete' elements from set\n3.Press 3 for diplay set\n4.Press 4 to exit" << endl;
cout << "please enter your option:";
cin >> op;
switch (op)
{
case 1:
cout << "enter the integer to add:";
cin >> val;
s.setMethod(val, setter);
if (s.addMembers() == 1) {
setter.insert(val);
cout << "The element is added successfully." << endl;
}
else {
cout << "The element is already present."<<endl;
}
break;
case 2:
cout << "enter the integer to delete:";
cin >> val;
s.setMethod(val, setter);
if (s.delMembers(val) == 1) {
setter.erase(val);
cout << "The element is deleted." << endl;
}
else {
cout << "The element is not present."<<endl;
}
break;

case 3:
s.display(setter);
break;
  
case 4:
choice = 0;
exit(0);
break;
}
}
  
}

OUTPUT:
