nested if — вложенные проверки if с переполнением стека

Может быть, мой код небрежный, но по какой-то причине он просто проходит через все вложенные проверки If, не останавливаясь, чтобы проверить ответ, кроме первого. Кроме того, первая проверка If переходит к вложенному If for True независимо от того, что даже если я даю неверный ответ. Я довольно новичок в C ++, так что, мне чего-то не хватает?
