What happens when you attempt to compile and run the following code?
#include <iostream>
#include <algorithm>
#include <vector>
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<int> 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:
