Support automatic memory management with reference counting ▪ Are C++ answer to garbage collection ▪ Release the resource if the smart pointer goes out of scope ▪ Are available in four versions raii.cppOverview Can be specialized for arrays: std::unique_ptr 7std::unique_ptr Function Description uniq.release() Returns a pointer to the resource and releases it uniq.get() Returns a pointer to the resource Classic problem ▪ If std::shared_ptr builds a cycle, no std::shared_ptr will be deleted automatically Rescue: ▪ std:weak_ptr breaks the cycle 16 Node Node Node NodeCyclic References 17

generate a xvalue, which is referenced by the moving structure of A (A(A&&)), thus extending the life cycle, and taking the pointer in the rvalue and saving it to obj. In the middle, the pointer to the xvalue corresponding memory of the deleted element. In this case, you need to manually run shrink_to_fit() to release this part of the memory. std::vector v; std::cout << "size:" << v.size() << std::endl; // deleted. In traditional C++, “remembering” to manually release resources is not always a best practice. Because we are likely to forget to release resources and lead to leakage. So the usual practice is

bigger fish to fry." Fair enough; we did. The prevailing attitude then was the "tick - tock" release cycle. C++11: big C++14: small (ish?) C++17: big?WORKING THE PROBLEM So I go away and let the issue

Simple; 2D, 2.5D mostly. ● Single threaded. ● Made from scratch (no game engine). ● Short release cycle. ● Small, by modern standards.Today: ● 3D, Photorealistic, Physics based. ● Multi-threaded
