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

#include

#include <algorithm>

#include

using namespace std;

void myfunction(int i) {

cout << " " << i;

}

void multiply (int a) {

a*2;

}

int main() {

int t[] = { 10, 5, 9, 6, 2, 4, 7, 8, 3, 1 };

vector v1(t, t+10);

for_each(v1.begin(), v1.end(), multiply);

iter_swap(v1.begin(),t+9);

for_each(v1.begin(), v1.end(), myfunction);

return 0;

}

Program outputs:
