No, Applications do not automatically delete themselves ever.
But from where exactly are you trying to log out?
Logging out from iCloud has nothing to do with your apps. Logging out from iCloud will cut the link between your iOs device and iCloud. But will not affect apps at all.
Logging out from iTunes and App Stores, will simply mean you cannot download anything until you log back in.
All apps will remain in place.
however, if you plan on logging in to the iTunes and App stores with a different Apple ID, know that downloading past purchases from another Id will lock you out of the previous ID for 90 days. i.e you won't be able to log back in to the original Apple ID for 90 days.
