Question

In an event-controlled loop, we know the number of times that the actions found inside the body of the loop will be executed.

a) True
b) False

Answer 1

The statement is false, as event-controlled loops run based on a condition being true rather than a predetermined number of iterations. These loops are commonly used when the number of iterations cannot be determined in advance.

Step-by-step explanation:

The statement given is false. In an event-controlled loop, we do not know the number of times the actions inside the body of the loop will be executed beforehand. The loop continues to execute as long as a certain condition is met or an event occurs, and it stops when the condition is no longer true or the event does not occur.

For example, a while loop in programming runs 'while' a specified condition is true and terminates when the condition becomes false. Unlike a count-controlled loop, such as a for-loop where we specify the number of iterations explicitly, an event-controlled loop is governed by the occurrence or non-occurrence of a specific event or state. This kind of loop is useful in scenarios where the number of iterations needed cannot be determined before entering the loop, such as waiting for user input or reading a file until the end is reached.
