У меня есть работающая программа, которая принимает размерности двух массивов и проводит их сложение, вычитание и умножение. Также все парные эл. массива нужно умножить на 3. И надо найти минимальное значение каждого из введенных массивов.
Я реализовала ее для целых и действительных чисел, но я не могу понять как реализовать для простых дробей.
