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

#include

#include

#include

using namespace std;

int main(){

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

vectorv(myints, myints+10);

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

set > s2(v.begin(), v.end());

for(set::iterator i=s1.begin();i!= s1.end(); i++) {

cout<<*i<<" ";

}

for(set >::iterator i=s2.begin();i!= s2.end(); i++) {

cout<<*i<<" ";

}

cout<

return 0;

}

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

#include

#include

#include

using namespace std;

template void print(T start, T end) {

while (start != end) {

std::cout << *start << " "; start++;

}

}

int main(){

vectorv;

set s;

for(int i=10; i>0; i??) {

v.push_back(i);

s.push_back(i);

}

print(v.begin(), v.end()); print(s.begin(), s.end());cout<

return 0;

}

The output will be:
