2D Array

[porkshopp]

I have this line of code to print the content of a 2d array, but it doesn't output anything. I have no idea what is wrong.

for (int k = 0; k < a; k++)
            {
                for (int h = 0; h < 0; h++)
                {
                    Console.WriteLine(Selection[k, h]);
                }
            }

a is the length of the array

C# for statement | Microsoft Docs

The condition section, if present, must be a boolean expression. That expression is evaluated before every loop iteration. If the condition section is not present or the boolean expression evaluates to true, the next loop iteration is executed; otherwise, the loop is exited.

Then look at the condition of your second loop.

Consider using Array.GetLength(Int32) Method (System) | Microsoft Docs as limit in condition.
