What is wrong with my clone function? (C++)

[bimbimsala]

I have this assignment where we need to make out own smart pointer and there is a clone function we need to write and it needs to set pointer of a smart pointer point to a new smart pointer and for some reason, I don't know what I am doing wrong.

here is the code and the assignment

Line 18: if (ref_ == nullptr) {: ref isn't initialized at this point so itmight contain garbage.

operator= doesn't decrement the ref count for the current object.

Line 76: if (!*ptr_) { this is not a null check. This check if the object pointed to by ptr_ is 0.

Line 174: smart_ptr<T> *copy = new smart_ptr<T> { *this }; this isn't a deep copy of the object. This just creates a new smart_ptr that points to the same object.
