Which of the following best describes a 'do/while' loop?

A 'do/while' loop is characterized by its behavior of checking the loop's termination condition at the end of the loop. This means that the block of code contained within the loop will execute at least once before the condition is evaluated. If the condition is true after the first execution, the loop will continue to run additional iterations based on that condition. This feature differentiates it from a 'while' loop, which evaluates the condition at the beginning and may not execute at all if the condition is false initially.

Given this structure, the option stating that a 'do/while' loop checks the condition at the end of the loop accurately captures its operational principle, highlighting its capability of ensuring that the loop body is executed at least one time, which is a fundamental aspect of its design. This uniquely allows scenarios where certain actions must be performed before deciding if further iterations are necessary.
