In Haskell, counter-controlled loops can be simulated by a function that takes the counter and a function as parameters, and executes the function repeatedly using recursion. a. Trueb. False

(A) True

Explanation:

Count-controlled loops use a counter (also referred to as loop index) which counts specific items or values and causes the execution of the loop to terminate when the counter has incremented or decremented a set number of times. Event-Controlled loops use an event to control the iteration of the loop.

Count-Controlled Repetition

Count-controlled repetition requires

A count-controlled repetition will exit after running a certain number of times. The count is kept in a variable called an index or counter. When the index reaches a certain value (the loop bound) the loop will end.

Count-controlled repetition is often called definite repetition because the number of repetitions is known before the loop begins executing. When we do not know in advance the number of times we want to execute a statement, we cannot use count-controlled repetition. In such an instance, we would use sentinel-controlled repetition.
