Начинающий C ++ избегает повторяющихся операторов if / else if

Я работаю над программой рассадки. Цель программы — показать таблицу мест с ценами на места и позволить пользователям выбрать либо конкретное место, либо место на основе цены. У меня все получилось, за некоторыми исключениями.

Я написал здесь с вопросом об одном из этих исключений, но был быстро проинформирован, что сначала мне нужно было решить вопрос с повторяющимся кодом для каждой цены. Мне нужно выяснить один кусок кода, который будет реализовывать это для каждого ценового диапазона. Я посмотрел это, но не совсем уверен, с чего начать. Какие-либо предложения?

"Row 7:  ",
"Row 8:  ",
"Row 9:  ",
