What type of loop executes a set number of times before terminating?

A fixed loop is designed to execute a predetermined number of times before it terminates. This is typically achieved by using a counter variable that tracks how many times the loop has run. For example, in languages like Python, a fixed loop can be implemented using the for statement, which iterates over a sequence, ensuring that the loop executes a specific number of times based on the range defined.

In contrast, an infinite loop continues to run indefinitely due to a failure to meet its terminating condition, and a conditional loop, often based on while statements, operates as long as a specified condition remains true, which may result in an unpredictable number of iterations. Nesting loops involve placing one loop within another, which can lead to more complex execution patterns rather than a set or fixed number of iterations. Thus, the nature of a fixed loop ensures that the execution count remains constant, directly addressing the requirements of the question.
