See how that works? As row gets higher, now the max value gets lower.

It may be a little less confusing if you define a function, print_row_of_asterisks(int numberOfAsterisks), and just call that function in a single loop. The loop inside the function should then be easy to figure out.

Also, the code will look a lot cleaner.
