Do smart pointers delete memory defined by new

In the following code example, does the destructor of the shared pointer delete the object that's been destructed defined by new?

auto object = std::shared_ptr<Foo>(new Foo());

I found this in some legacy code and I'm wondering if this causes memleaks or not.

Yes, it does that – Wander3r Jan 10 '20 at 09:44
@Wander3r To clarify: It does delete the memory. It does not cause memory leaks. – Max Langhof Jan 10 '20 at 09:52
@MaxLanghof Didn't realize there's an opposite question to what's asked in the title :) – Wander3r Jan 10 '20 at 10:01

*"I found this in some legacy code"* C++11 is already legacy... – Jarod42 Jan 10 '20 at 10:07

@Jarod42 Arguably using the pattern `shared_ptr(new T)` *is* legacy code, since you’re supposed to use `make_shared()` unless there’s a specific reason against it. – Konrad Rudolph Jan 10 '20 at 11:21
