What type of loop is used in this given code?

The code in question employs a do-while loop, which is distinguished by its structure that allows the loop body to execute at least once before evaluating the condition to determine if it should continue. This is because the condition check occurs after the loop's statements have been executed.

The defining characteristic of a do-while loop is the placement of the condition check at the end of the loop, which guarantees that the statements within the loop will run a minimum of one time, regardless of whether the condition is initially true or false.

In contrast, a for loop typically involves initialization, a condition that is checked before each iteration, and incrementation, making it suited for scenarios where the number of iterations is known in advance. A while loop also checks its condition before entering the loop, which can lead to scenarios where the loop might not execute at all if the condition is false initially. An infinite loop would continuously execute without terminating under any condition, which is not the case here since the loop is structured to stop based on a conditional check at the end.

Thus, the presence of the condition at the conclusion of the loop block combined with its guaranteed initial execution supports the identification of the loop type as a do-while loop.
