This article shows you how to use unique_ptr in C++. The content is concise and easy to understand. It will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

Unique_ptr is one of the smart pointers provided by C++ 11 to prevent memory leaks and enjoys exclusive ownership of managed object pointers. The unique_ptr object wraps a raw pointer and is responsible for its life cycle. When the object is destroyed, the associated original pointer is deleted in its destructor.

Unique_ptr has the-> and * operator overloads, so it can be used like a normal pointer.

View the following example:

# include

# include

Struct Task {

Int mId

Task (int id): mId (id) {

Std::cout
