#contain iostream #contain cmath int substantial() {     int x, y, len = 0;     std::cout << "enter a 5 digit quantity: ";     std::cin >> x;     y = x;     mutually as ( y % 10 ) {         y = floor( y / 10 );         len++;     }     if ( len != 5 ) {         std::cout << "Invalid quantity";     } else {         for (int i = len - one million; i >= 0; i--) {             std::cout << (x % 10) << std::endl;             x /= 10;         }     } }
