question 35
a(n) ___ is very similar to a counter that you use to count loop iterations, except that you usually add a value other than one to this type of variable.
total
accumulator
transaction
validator

Explanation:

1. In programming, a sentinel value is used to control loop repetitions. It acts as a signal to stop the loop. For example, in a loop that reads user input until a specific value (the sentinel) is entered.
2. An accumulator is similar to a counter. While a counter typically increments by 1 each iteration (to count the number of loop runs), an accumulator can add a value other than 1 (e.g., summing up a series of numbers entered by the user in a loop).

Answer:

1. A. sentinel value
2. B. accumulator
