srand(time(NULL));
for
(i = 0; i < 40; i++)
{
{
loc += rand() % 3 - 1;
//cout << loc;
}

for (j = 0; j <= loc; j++)
{
cout << ".";
}

using namespace std;

int main()

	srand(static_cast<unsigned int>(time(nullptr)));

	for (int i = 0, loc = 40; i < 40; ++i) {
		loc += rand() % 3 - 1;
		cout << setw(loc) << setfill('.') << '.' << "*" << setw(79 - loc) << setfill('.') << "\n";
	}
