Написал курсовую работу на СИ, требуется ввести текст а далее с ним будут различные манипуляции, и когда я ввожу текст, ничего не происходит, нажимаю Enter, и консоль просто переходит на новую строку, а если нажимать ctrl + d то ввод принимается и программа завершается, а мне нужно еще выбрать пункт меню, но она сразу завершается
