How many times is a do..while loop guaranteed to execute?

The do..while loop is a control flow statement that is similar to the while loop but with a key difference: it guarantees that the code within the loop will execute at least once. This is because the condition that determines whether to continue looping is evaluated after the loop's body has been executed.

In other words, regardless of whether the condition is true or false on the first evaluation, the block of code inside the do..while loop will run a minimum of one time. This is particularly useful in scenarios where the initial execution of the code is necessary to set up the state for further iterations.

For example, if you are reading input from a user and want to ensure they are prompted at least once, a do..while loop would be an ideal choice. After the first execution, the condition is then evaluated, and if it evaluates to true, the loop executes again; if it's false, the loop terminates.

Other options don't embody this essential characteristic of the do..while loop.
