2. Sentinel valueIn computer programming, a sentinel value (also referred to as a flag value, trip value, rogue value, signal value, or dummy data) is a special value whose presence guarantees termination of a loop that processes structured data. The sentinel value makes it possible to detect the end of the data when no other means to do so (such as an explicit size indication) is provided.
