   What is a sentinel value in programming?

   • In programming, sentinel value acts like a signal, helping the program identify specific conditions or events. For instance, the null character (‘\0’ or simply NULL) can be used to mark the end of a string. Sentinel values are typically associated with the manipulation of sequential data structures, like lists.

   What is a sentinel value in a loop algorithm?

   • The sentinel value typically is chosen so as to not be a legitimate data value that the loop will encounter and attempt to perform with. For example, in a loop algorithm that computes non-negative integers, the value “-1” can be set as the sentinel value as the computation will never encounter that value as a legitimate processing output.

   What is a Sentinel controlled loop?

   • A sentinel controlled loop is also called an indefinite repetition loop because the number of iterations is not known before the loop starts executing. In a sentinel controlled loop, a special value called sentinel value is used to change the loop control expression from true to false in order to determine whether to execute the loop body.
