I won’t cover the process of unit testing the recursive implementation. It is simple enough that, for the purposes of this blog post, I’ll take its correctness as a given. What I’ll focus on here is the step where we convince ourselves that the two implementations are interchangeable.

This USB flash drive is FIPS Certified 197 and has 256-bit AES-XTS encryption. It offers protection against brute-force attacks and BadUSB. Manufactured in the US, this drive is TAA-compliant. Kingston suggests read and write speeds around 250 MB/s and 180 MB/s, respectively, but it did a little better than that in our tests (around 300 MB/s and 220 MB/s for larger files). Offered in USB-A or USB-C models, in sizes ranging from 8 to 512 gigabytes, this drive comes with a five-year warranty.。新收录的资料是该领域的重要参考
SummaryIf you want to have good performance for your singleton implementation and you need to provide a constructor, you should go for the static data member implementation. In case you can default the default constructor, the two implementation strategies are equivalent performancewise. I would suggest using the block local approach as it saves having to define and initialize the singleton object in an implementation file.
