What will be the output of the following C++ code?

#include <iostream> 
#include <functional>
#include <algorithm>
using namespace std;
int main () 
{
    int numbers[] = {3, -4, -5};
    transform ( numbers, numbers + 3, numbers, negate<int>() );
    for (int i = 0; i < 3; i++)
        cout << numbers[i] << " ";
}
