Where is shared_ptr?

Question

I am so frustrated right now after several hours trying to find where shared_ptr is located. None of the examples I see show complete code to include the headers for s

Answer 1

There are at least three places where you may find shared_ptr:

1. If your C++ implementation supports C++11 (or at least the C++11 shared_ptr), then std::shared_ptr will be defined in .

2. If your C++ implementation supports the C++ TR1 library extensions, then std::tr1::shared_ptr will likely be in (Microsoft Visual C++) or (g++'s libstdc++). Boost also provides a TR1 implementation that you can use.

3. Otherwise, you can obtain the Boost libraries and use boost::shared_ptr, which can be found in .
