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。
Raw pointer allocated with new and released with delete. Description Use astd::unique_ptrinstead. Limitations Checklist for review Some things are not automated, and forgotten often. This list is a reminder for the reviewers. The bug fix is important enough to be backported? (label: 'backport ...

For example, unique_ptr is safe, and decays to almost nothing, to a raw pointer under the hood. Hence, any memory access made by using this pointer is as cheap as a usage of raw pointer. Accessing a shared_ptr is also as fast as a raw pointer, but when copying, shared_ptr needs ...
