I want to use smart pointer in my c++ application.

Which header file I should include for using std scoped_ptr?

May I know the reason for vote down – Fellowship

scoped_ptr is not a standard smart pointer, it is provided by Boost. C++11 introduced std::unique_ptr, which is similar to scoped_ptr with the exception that it is movable. As to the headers where these can be found, this information can very easily be found in the respective documentations. – Internal

I downvoted your question because it does not show any research effort: the StackOverflow users are not a replacement for documentation, where you could have found this information. – Internal

For the differences between boost::scoped_ptr and std::unique_ptr, see this question and this one. – Internal

@LucTouraille Please see this link link Here, something std::tr1::scoped_ptr is mentioned in Lloyd's answer – Fellowship

@Lloyd's answer is wrong, there is no std::tr1::scoped_ptr – Joyjoya

@LucTouraille Actually, the boost docs don't explicitly say which header file to use: boost.org/doc/libs/1_55_0/libs/smart_ptr/scoped_ptr.htm - it's buried in example code – Britzka

Answer 1

There is no scoped_ptr in the standard C++ library. All C++11 smart pointers are in header <memory>. If you want boost::scoped_ptr then you need boost/scoped_ptr.hpp.

There is no scoped_ptr in the namespace std.
You can either use boost::scoped_ptr from boost.
Or I guess you wanted std::unique_ptr.In this case you need to include <memory>

Answer 3

scoped_ptr is a part of Boost library, not standard library.
