using namespace std;
void myprint(int i) {
cout << i << ", ";// Line I
}
int main() {
int mynumbers[] = { 3, 9, 0, 2, 1, 4, 5 };
vector<int> v1(mynumbers, mynumbers + 7);
set<int> s1(mynumbers, mynumbers + 7);
deque<int> d1(mynumbers, mynumbers + 7);
d1.pop_front();// Line II
for_each(v1.begin(), v1.end(), myprint); // Line III
for_each(s1.begin(), s1.end(), myprint);
for_each(d1.begin(), d1.end(), myprint);
