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

#include

#include

#include <algorithm>

using namespace std;

templatestruct Out {

ostream & out;

Out(ostream & o): out(o){}

void operator()(const T & val ) {

out<

}

};

struct Sequence {

int start;

Sequence(int start):start(start){}

int operator()() { return start++; }

};

struct Odd { bool operator()(int v) { return v%2==0; }};

int main() {

vector v1(10);

generate(v1.begin(), v1.end(), Sequence(1));

partition(v1.begin(),v1.end(), Odd());

for_each(v1.begin(), v1.end(), Out(cout) );cout<

return 0;

}
