Accessing a set of pointers - c++

Question

Here is my code:
class obj140{
public:
int x;
explicit obj140(int y):x(y){ }
bool operator<(const obj140& rhs) const{
return x < rhs.x;
}
};
int main() {
obj140 * wtf = new obj140[5] {obj140(1),obj140(1),obj140(3),obj140(4),obj140(5)};
std::set<obj140> orm(wtf,wtf+5);
}
Is this possible? like copying pointers to a set? I have no errors but I have no idea on how to access it though.
How do i print out the values from orm set?

I modified your code slightly to make what's going on easier to see and as an example of one way to get a look at the items stored in the set.
class obj140
{
public:
int x;
explicit obj140(int y) :x(y)
{
}
bool operator<(const obj140& rhs) const
{
return x < rhs.x;
}
void print() const
{
std::cout << x << std::endl;
}
};
int main()
{
obj140 * wtf = new obj140[5]
{ obj140(1), obj140(1), obj140(3), obj140(4), obj140(5) };
std::set<obj140> orm(wtf, wtf + 5);
for (auto it = orm.begin(); it != orm.end(); ++it)
{
it->print();
}
delete[] wtf; //edit. Forgot to clean up the pointer.
return 0;
}
Output:
1
3
4
5
What you are doing works and loaded the set. Since sets only store unique values (and order them, which makes for a great quickie sort if you need one) the second add of obj140(1) got discarded.
