What is a key characteristic of the Do While loop?

The key characteristic of the Do While loop is that the condition is evaluated after each execution of the loop statements. This means that the block of code inside the loop will execute at least once, regardless of whether the condition is initially true or false. The loop continues to run as long as the condition evaluates to true, so even if the condition turns false on subsequent checks, the loop will have performed its operation at least one time.

This behavior is particularly useful in scenarios where at least one iteration is needed, such as when user input is required that must be processed before a decision on continuation can be made or when an action needs to happen first before checking a condition. Thus, it creates a structure that guarantees execution before any conditions are checked again, ensuring that essential tasks are performed right away.
