Question 1

What happens when you attempt to compile and run the following code? Choose all that apply.

#include <iostream>
#include <set>
#include <vector>
#include <functional>
using namespace std;

int main(){
int mynumbers[] = { 3, 9, 0, 2, 1, 4, 5 };
vector<int> v(mynumbers, mynumbers+7);
set<int> set1(v.begin(),v.end());
set<int, greater<int> > set2(v.begin(), v.end()); //LINE I
for(set<int, int>::iterator i=set2.begin();i!= set2.end(); i++)
cout<<*i<<" ";
for(set<int>::iterator i=set1.begin();i!= set1.end(); i++)
cout<<*i<<", ";
cout<<endl;
return 0;
}




program outputs: 9 5 4 3 2 1 0 0, 1, 2, 3, 4, 5, 9,



program outputs: 0 0 1 2 3 4 5 9, 1, 2, 3, 4, 5, 9,



compilation fails due to error in line I



code compiles and executes successfully

, program outputs: 9 5 4 3 2 1 0, 1, 2, 3, 4, 5, 9,

}




the size of the s1 set is 7



program outputs: 0, 1, 2, 3, 4, 5, 9,



program outputs: 0, 1, 2, 3, 4, 5, 9, 10,



the size of the s1 set is 8



program outputs: 0, 1, 2, 3, 4, 5, 10,
