Explanation / Answer

1)

#include <iostream>
using namespace std;

int main()
{
int val=0;

// continue until eof
while(!cin.eof())
{

// take input
   cin>>val;

// display value
   cout<<val<<" ";
}
   return 0;
}

2)

#include <iostream>
#include <set>
using namespace std;
int main ()
{

// declare set of string
set<string> s;
string str;
// set of string does srting of its own
while(!cin.eof())
{
cin>>str;
s.insert(str);
}
cout << "Set contains:";
while (!s.empty()) {
cout << ' ' << *s.begin();
s.erase(s.begin());
}
  
return 0;
}

4)

#include <iostream>
#include <list>
using namespace std;
int main ()
{
list<int> s(4,100);
for (list<int>::iterator it = s.begin(); it != s.end(); it++)
cout << *it << ' ';

cout << ' ';

return 0;
}
