Description

Description

Hello.

I have checked project using the PVS-Studio analyzer. The results of the check revealed a number of suspicious code fragments that I have included in an article. You may be interested in taking a look at them.

It's worth noting that the article contains only the most interesting warnings issued by the analyzer. You can check your project in more detail using the free version of PVS-Studio for open-source projects.
