Question 1
pts
What will happen when you attempt to compile and run the following code?

#include <iostream>
#include <algorithm>
#include <vector>
#include <deque>
#include <set>
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);
return 0;
}




compilation error in LINE II



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

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



the exception will be thrown at LINE II



the exception will be thrown at LINE III



compilation error in LINE I



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



Question 2

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

#include <iostream>
#include <algorithm>
#include <vector>
#include <deque>
#include <set>
using namespace std;

struct myprinter {
void operator() (int i) {cout << i << ", ";}
};

int main() {
int mynumbers[] = { 3, 9, 0, 2, 1, 4, 5 };
vector<int> v1(mynumbers, mynumbers + 7);
deque<int> d1(mynumbers, mynumbers + 7);
set<int> s1(mynumbers, mynumbers + 7);
v1.pop_back(5);// Line I
for_each(s1.begin(), s1.end(), myprinter()); // Line II
for_each(d1.begin(), d1.end(), *(new myprinter())); // Line III
for_each(v1.begin(), v1.end(), myprinter); //Line IV

, return 0;
}




compilation error in LINE III



compilation error in LINE IV
