How does iteration terminate?

Iteration typically refers to the process of repeatedly executing a set of instructions within a loop until a specified condition is no longer true. The correct answer highlights that iteration terminates when the loop continuation condition fails. This means that the loop will continue to run as long as its defined condition remains satisfied. Once that condition evaluates to false, the loop will exit, effectively terminating the iteration process.

In programming, loop structures—such as while loops or for loops—are built around this mechanism. The condition that governs the continuation of the loop is fundamental to managing the control flow during iteration. When designing loops, programmers need to ensure that the conditions properly reflect the desired outcome to avoid infinite loops or premature termination.

While recursion involves a condition related to function calls, and changes in global variables can influence the state of an application, these aspects do not directly determine the termination of an iteration process. The exit of a function scope relates to terminating the execution of a function rather than the iteration itself. Hence, identifying the failure of the loop continuation condition is essential for understanding how iterations conclude in programming contexts.
