How to make a reference to an object in unity in C#?

Question

C++ / C#

Hello, can anyone help? In unity, the non-static method UnityEngine.Component.transform.get requires a reference to an object. The error appears on line 16 with error CS0120. Due to the fact that I just started learning C #, I don’t understand what needs to be added. If it's easy, please describe in more detail. Thanks in advance!
