1. Predict the output of this program. ``

cpp
#include <iostream>
using namespace std;

int main() {
    cout << -7 / 2 << ' ' << 7 / -2 << ' ' << -7 % 3 << endl;
    return 0;
}

``

-4 -4 -1-3 -3 -1-3 -3 1-4 -3 -1

2. Predict the output of this program. ``

cpp
#include <iostream>
using namespace std;

int main() {
    cout << -10 % 4 << ' ' << 10 % -4 << ' ' << -10 / 4 << endl;
    return 0;
}

``

-2 -2 -22 2 -3-2 2 -2-2 2 -3

3. Predict the output of this program. ``

cpp
#include <cmath>
#include <iostream>
using namespace std;

int main() {
    cout << floor(-9 / 4) << ' ' << floor(-9 / 4.0) << endl;
    return 0;
}

``

-2 -3-3 -3-2 -2-3 -2

4. In C++, what does 7 % -2 evaluate to when both operands are int?

-1-301

5. What does floor_mod(-1, 5) return, using the helper from this lesson?
