About the principle of operation

[AiXanadu]

Hello everyone, I would like to ask, can someone describe the rationale for the update procedure?
I don't know much about OC.
Is it possible to achieve the same functionality in C++?

Under what kind of operation is this open source project, the application can be updated without entering a password?

Sparkle is a software update framework developers use to update their apps.. This is not a good question.

I don't know much about OC.

I don't know what OC stands for.

Is it possible to achieve the same functionality in C++?

Sparkle, being written for macOS, uses Apple's APIs which are written in Obj-C. It's feasible to use Sparkle from Obj-C++ (for example we have documentation for using Sparkle from Qt on the website).

Under what kind of operation is this open source project..

It's open source..

the application can be updated without entering a password?

Depends. If you ship an app (not a pkg) then for most users yes (unless user is a non-admin user and the app is owned by admin user, or app is owned by root user because some other user feels like doing that).
