Извините, если я разместил слишком много кода. Я действительно не знаю, откуда исходит ошибка ссылки. Кажется, есть проблема с этой строкой:
dough = ingredientFactory->createDough();
в классе CheesePizza, но я не знаю, является ли ссылка componentFactory или проблемой в классе Dough. Может кто-нибудь сказать мне, почему он не будет ссылаться? (Я получаю ошибку LNK1120). Любая помощь будет принята с благодарностью.
Спасибо.
