signature

Hello there! Here's a recent one (which is perhaps strange) I found that in C++ it is possible to set function signatures in ... ? Unlimited number of parameters? If so, what variable is it set to, i.e. how to access them? Can you please explain? Thanks!

I exported the app to a .apk file, installed it. Then, when I run the application through debugging, it requires reinstalling ... at, I worked under Windows, such a problem was not observed, I even specially flashed the axis on the phone, you never know.
