Окно консоли C ++ мигает, а затем исчезает

Итак, вот калькулятор налога с продаж, который я сделал, и окно консоли мигает, а затем исчезает. Просто интересно, что я сделал не так. Также я чувствую, что юнит-тест встроен в сам код, но мне было интересно, как юнит-тест будет применяться к таким параметрам.
