вот уже сегодня первый раз написал простенькую программу,мне понравилось,сразу после этого в книге пригигантская программа,которая считывает координаты точек,и в конце выводи площадь прямоуголника...вот коды

сразу нашел около 20 ошибок...не могу уже 4часа работаю сил не хватает
вот эти геморные ошибки,у меня уже не мозг а геморой
ошибки
Обратите внимание на loaction, книге вообще об этом не гвоорится,и я не знаю,объект ли это,или же член
