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

#include

#include

#include

using namespace std;

templateclass B { T val;

public:

B(T v):val(v){}

T getV() const {return val;} bool operator < (const B & v) const { return val

templateostream & operator <<(ostream & out, const B & v) { out<

out;}

templatestruct Out {

ostream & out;

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

void operator() (const T & val ) { out<

bool Less(const B &a, const B &b) { return int(a.getV())

int main() {

float t[]={2.28, 1.66, 1.32, 3.94, 3.64, 2.3, 2.98, 1.96, 2.62, 1.13};

vector > v1; v1.assign(t, t+10);

stable_sort(v1.begin(), v1.end(), Less);

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

return 0;

}
