RE:Recursion

[lordango]

can someone explain to me the program flow of this code:

class Program
    {
        static void Main(string[] args)
        {
            Program.count(1);

            Console.ReadKey();
        }
        static int count(int i) {

            Console.WriteLine(i);
            if (i < 10) {
                Console.WriteLine(count(i+1)+(i-1));
            }
            return 1;
        }
    }

Thank you very much in advance.

Sounds like you copied, not sure why else you don't understand. Not sure what you are trying to achieve...

The output is:
1
2
3
4
5
6
7
8
9
10
9
8
7
6
5
4
3
2
1

I did the code (trial and error) i did not copied it. I saw the problem on the internet to display 1-10 then 10-1 so i did.
I can follow from 1-10 but after that im confused because i tried changing the value of return 0 and the output changes. I just want to know how does the return 0 affects the output.

Can you please show me the program flow?

I tried to use F11 + addwatch but still i can trace the part where the recursion happens.
Did the function stored the return values while it was recursing or is it using the return 0?

Thank you. and again i did not copy it. I did it by trial and error.

So what about this thread where someone has already helped you step through a different recursive program?

The experts here are not necessarily teachers...I suggest that you get a recursion tutorial (recursion is just logic, so it can be in any language) and read it. Once you understand the theory behind recursion, these problems aren't as confusing.
