Thread: How to draw shapes with only for loops?

Ok I have this problem.

First I need to make a right triangle:

#
##
###

Done.

Then I need to make an opposite right triangle:

- #
-##
###

(I hope you know what I mean. Not any isosceles triangle, just the same triangle but the opposite.)

Not done.

Here is the code I used for the first one:

Code:

	for (int row = 0; row < 10; row++)
	{
		for (int col = 0; col <= row; col++)
		{
			cout << "#";
		}
		cout << "\n";
	}

For the second one my code was this, but the problem is that I can't use the int count = row - 2, and the if statement that goes along with it. I can only use another for loop.

Code:

for (int row = 0; row > 3; row++)
	{
		int count = row - 2;
		for (int col = 0; col > 3; col++)
		{
			count ++;
			if ( count - 1 == 0 )
			{
				cout << "#";
			}
			else {cout << " ";}
		}
		cout << "\n";
	}

Can anyone help me with this? I need another for loop added to the original code for the first right triangle.
