Which of the following loops should you use if a loop must run at least once even if the condition is false?

The do while loop is the appropriate choice when you need a loop that guarantees execution at least once, regardless of whether the condition evaluates to true or false.

In a do while loop, the block of code is executed first, and then the condition is checked after the execution. This behavior ensures that even if the condition evaluates to false on the first check, the statements inside the loop will still run once before the condition is evaluated. This contrasts with other types of loops such as the for, while, and forEach loops, which check the condition before executing the loop body. If the condition is false at the outset in those cases, the code within the loop will not execute at all.

For example, if you have a task that must perform an initial setup or operation before checking a repeat condition (like prompting a user for input), a do while loop is ideal for ensuring that the operation happens at least once.
