#include<bits/stdc++.h>
using namespace std;

int main()
{
srand(time(NULL)); //srand function to generate different random number every time
  
//create a container using set that will store 100 random numbers in descending order

//greater<int> is a functor used to keep the numbers in descending order
set<int,greater<int> > s;
  
//generate and insert 100 random numbers in a set
for(int i=0;i<100;i++)
{
int temp=rand()%5000;   //use %5000 to generate numbers less than 5000. we can use any number instead of 5000
s.insert(temp);
}
  
cout<<"100 random numbers in descending order are : \n";
  
set<int,greater<int> >:: iterator it=s.begin(); //iterator to traverse the set
  
//traverse whole set and print the content
while(it!=s.end())
{
cout<<*it<<" ";
it++;
}
}
