Методы оценки эффективности инвестиций и обоснование их экономической целесообразности по проекту
Задание №37
Расположить в матрице A(N,N) элементы в
последовательности указанной на рисунке.
Требования к программе:
1.
Составить
программу на алгоритмическом языке, выполняющую указанные преобразования с
матрицами;
2.
Вывести вектор,
полученный случайно;
3.
Вывести
преобразованную матрицу с новым содержимым вектора;
4.
Программа должна
строиться таким образом, чтобы существовала возможность её использования с
массивами любой размерности, содержащими произвольные элементы;
5.
В программе
должна быть предусмотрена выдача на печать исходных и преобразованных матриц;
6.
Полученные
результаты должны быть занесены в файл последовательного доступа и доступны для
просмотра из него.
