How to create an instance of shared_ptr? The below-mentioned example shows how to create instances of a shared pointer. /* Object ptr owns dynamically allocated int */ std::shared_ptr<int>ptr(newint); Now ptr is owing to the memory of unnamed integer object. Usingptryou can access this...

be used in library code. In library code, the delete operator can onlybe used in destructors. In application code, memory must be freed the object that owns it. Examples: The easiest way is to place an on thestack, or make it a member of another class. For a large number...
This lets us read thechar *strpointer. If we could control the value ofstr, we could use this to arbitrary read. 3.2. "Delete result" case2:puts("Result deleted"); result.reset();return; It callsstd::unique_ptr<Request>::reset, which destructs theRequestand frees it. So we can tot...
