How recursion works in C#

Question

Here\'s my code

using System;
public class Program
{
   public static void Method(int flowerInVase)
      {
         if (flowerInVase > 0)
         {
             


        

Answer 1

The structure of the calls look like this. Maybe this visualization will help you understand why the numbers print 1, 2, 3 and not 3, 2, 1:

Method(3);
  flowerInVase > 0 ?
  Yes - Method(2);
    flowerInVase > 0 ?
    Yes - Method(1);
      flowerInVase > 0 ?
      Yes - Method(0);
        flowerInVase > 0 ?
        No
      WriteLine(1);
    WriteLine(2);
  WriteLine(3);

The reason is because your call to Method(flowerInVase - 1) comes before the call to WriteLine(flowerInVase). Execution jumps to a different copy of the method before it has a chance to print the number it is on.
