Row and Colums excercise

Actually it doesn't. You are using same variable to iterate both the loops. In addition, you are using Console.WriteLine() out side the inner loop but inside the outer loop. That gives the effect row to you on the screen. Comment that and you will see all numbers in one row.

 

You can change, row and column variables to i and j the it will still have same effect.

 

If you are not happy with above answer, please clarify further about your question.
