c++: what's the difference between new Object() and Object()

Question

so in C++ you can instantiate objects using the new keyword or otherwise...

Object o = new Object();

but you can also just do

Answer 1

You can't do Object o = new Object(); The new operator returns a pointer to the type. It would have to be Object* o = new Object(); The Object instance will be on the heap.

Object o = Object() will create an Object instance on the stack. My C++ is rusty, but I believe even though this naively looks like an creation followed by an assignment, it will actually be done as just a constructor call.
