What happens when you attempt to compile and run the following code?

#include <iostream>

#include <set>

#include <vector>

using namespace std;

int main(){

int t[] ={ 3, 4, 2, 1, 6, 5, 7, 9, 8, 0 };

vector<int>v(t, t+10);

multiset<int> s1(v.begin(),v.end());

s1.insert(v.begin(),v.end());

pair<multiset<int>::iterator,multiset<int>::iterator> range; range = s1.equal_range(6); while (range.first != range.second) { cout<<*range.first<<" "; range.first++;

}

return 0;

}

What will happen when you attempt to compile and run the code below, assuming that you enter the following sequence:

one two three<enter>?

#include <iostream>

#include <string>

using namespace std;

int main ()

{

string a;

cin>>a;

cout<<a<<endl;

return 0;
