I have been told to obtain the factorial of 13 using a while loop, and the solution given is the attached one. I don´t really understand why it's used that code, and would appreciate if someone could give me some explanations about it. Thanks!!

Use breakpoint, run the code line by line, and check the values of variables at each step. You will clearly see what is happening.
