The unique_ptr class: A “unique_ptr” is a smart pointer which wraps the normal pointer into an owned object is referred as raw pointer. This object will manage or taking ownership of another object using pointer. It has an ability to take responsible for deleting the pointed object when it goes out of scope. It owns their pointer unique. It is parameterized by the type of an object it points to. Syntax: Consider the following syntax to create a “unique_ptr” pointer: unique_ptr<data_type> pointer_variable(new data_type); Example: unique_ptr<int> wrd(new int); In above statement, the variable “wrd” is declared as “unique_ptr” for int type.
