记录一次在cpp群里面的讨论过程。 首先是有人提出,没出C++11里面没有make-unique。 Why does C++11 have `make_shared` but not `make_unique`。答案忘记了。 然后就是老生常谈的,为什么需要make-unique,因为异…
make_unique is not part of C++11 but c++14. See: http://en.cppreference.com/w/cpp/memory/unique_ptr/make_unique Jan 20, 2015 at 7:39pm mutexe(2372) Balls. My mistake sorry. Jan 20, 2015 at 7:43pm closed account (SECMoG1T) ...

(简单)如果unique_ptr从new得到的结果构建而不是使用make_uinque,报警。 原文链接 https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md#r23-use-make_unique-to-make-unique_ptrs 觉得本文有帮助?请分享给更多人。 关注微信公众号【面向对象思考】轻松学习每一天!

使用raw指针和make_shared创建shared_ptr对象,优先使用make_shared,unique_ptr也一样,程序员大本营,技术文章内容聚合第一站。
