What type of loop executes a block of code at least once, regardless of the condition?

The do..while loop is designed to execute a block of code at least once before evaluating the condition that determines whether the loop will continue. This is a fundamental feature of the do..while loop: the code block inside the loop runs first, and only after its execution does the condition get checked. If the condition evaluates to true, the loop will run again; if false, the loop will terminate.

This characteristic makes the do..while loop particularly useful in situations where you want to ensure certain code executes at least once, such as prompting a user for input before verifying if that input meets specific criteria for continued processing.

In contrast, other loop types such as the for loop, while loop, and foreach loop check their conditions before potentially executing the code block. As a result, if the condition is not met initially, the code might not run at all.
