How is the factorial of a number obtained in a C# loop?

Question

C++ / C#

Hello gentlemen! Help me understand how it turns out for the for loop to calculate the factorial of the entered number, I understand that this formula produces a factorial, but how this happens, I can’t visualize the order of calculation.

int n = Convert.ToInt32(Console.ReadLine());
            int Foctarial = 1;
            for (int i = 2; i <= n; i++)
            {
                Foctarial *= i;
            }
            Console.WriteLine(Foctarial);

Answer 1

So what is there to visualize ... Let's say n is 5.
Build a table (just a table!) What is the Factorial variable at each iteration of the loop - i.e. starting from i==2 and ending with i==5.
