Webb4 aug. 2024 · Shallow copy pointers, including raw pointers, typically don’t propagate constness. It makes little sense for them to do so, as you can always obtain a non-const pointer from a const one and then proceed to modify the object through it. shared_ptr is "as close to raw pointers as possible but no closer".

Webb22 feb. 2024 · There is no memory management system for raw pointers. Therefore, not deleting the allocated memory of pointer explicitly causes memory leak: int x; int* p = new int; p = &x; In the above example, new int memory is an island in the sea of computer memory. We could only find it via p but, in the last line, p is pointed to another place, x.
WebbThe raw pointer overloads assume ownership of the pointed-to object. Therefore, constructing a shared_ptr using the raw pointer overload for an object that is already managed by a shared_ptr, such as by shared_ptr (ptr. get ()) is likely to lead to undefined behavior, even if the object is of a type derived from std::enable_shared_from_this. the outer man is decayingWebb11 nov. 2024 · In this article.
