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

#include

#include

#include

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++; } };

int main() {

vector v1(10);

vector v2(10);

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

reverse_copy(v1.begin(),v1.end(), v2.rbegin());

sort(v2.begin(), v2.end(), less_equal());

for_each(v2.begin(), v2.end(), Out(cout) );cout<<endl;

return 0;
