Posttest loops are control structures in programming that execute a block of code at least once before checking a condition to determine if it should repeat. The most common example of a posttest loop is the "do-while" loop, where the loop's body runs first and the condition is evaluated afterward. This ensures that the code within the loop is executed at least once, regardless of whether the condition is initially true or false. Posttest loops are useful when the initial execution of the code is necessary before any condition checks.
