What happens when you attempt to compile and run the following code?
#include < vector >
#include < iostream >
#include < algorithm >
using namespace std;
class B { int val;
public:
B(int v=0):val(v){}
int getV() const {return val;}
operator int () const { return val;} };
template < class T > struct Out {
ostream & out;
Out(ostream & o): out(o){}
void operator() (const T & val ) { out < < val < < " "; } };
struct Add {
B operator()(B & a, B & b) { return a+b; }};
int main() {
int t[]={1,2,3,4,5,6,7,8,9,10};
vector < B > v1(t, t+10);
vector < B > v2(10);
transform(v1.begin(), v1.end(), v2.begin(), bind1st(Add(),1));
for_each(v2.rbegin(), v2.rend(), Out < B > (cout));cout < < endl;
return 0;
}
